New Cornelia mine and the town of Ajo Spaniards mined on a small scale at Ajo as early as 1750. After the Gadsden Purchase brought the southern Arizona into the United States in 1853, the mine was reopened in 1855, and shipped high-grade ore to Swansea in Wales. However, the remote desert location made mining generally uneconomic without onsite treatment. The area was mostly idle until the New Cornelia mine opened in 1917 as the first large open-pit mine in Arizona.

Granby operated the Phoenix Mine, which comprised both an underground mine and open pit mine. The underground operation utilized a square-set mining method, but by 1901 had converted to an open stope and pillar method with considerable cost savings. The operation maintained a completely unsupported "show stope" which with dimensions of high, wide, and long. In 1903 the mine operated three small steam shovels to work in the surface operations producing half of the mines production, this made up one of the earliest attempts at open pit mining in British Columbia.

Maintenance of the underground movable machinery takes place underground, where the facilities and equipment required for water extraction, ventilation, electrification, communication and other infrastructure are also located. In addition to the currently active Elijärvi and Viia ore bodies, underground mining is beginning in the Surmaoja ore body alongside the other two ore bodies from level 500 upwards. Because of the mining method used, the ore extraction process in each ore body always proceeds upwards towards the bottom of the open-pit mine, while filling fully extracted areas with waste rock.

Peter Grubb founded the Cornwall Iron Furnace as well as the Cornwall iron mines, the richest source of iron ever found in America east of Lake Superior. In the 1730s, Grubb, a stonemason, began mining in what is now known as Cornwall, Pennsylvania, and literally stumbled upon one of the largest and richest iron mines ever found. (It was mined for over 240 years, until the open pit mine flooded in 1972). In 1742, Grubb built the Cornwall Iron Furnace which used a charcoal-fired blast furnace to convert iron ore to pig iron.

The Küttejõu open-pit mine was closed in 1947 and the Küttejõu underground mine was merged with the Kiviõli mine in 1951. The Ubja mine was closed in 1959. After construction of large oil shale-fired power stations, demand for oil shale increased and consequently new larger mines were constructed: the underground mines Viru (1965) and Estonia (1972) along with the open-pit mines Sirgala (1963), Narva (1970) and Oktoobri (1974; later named Aidu). Correspondingly, several exhausted smaller mines like Kukruse (1967), Käva (1972), No. 2 (1973), No. 4 (1975), and Kiviõli (1987) were closed.

Sydvaranger AS, previously A/S Sydvaranger, is an iron ore mining company operating in Sør-Varanger, Norway. Owned by the Tschudi Group, Sydvaranger owns an open-pit mine at Bjørnevatn and then hauls the ore with the Kirkenes–Bjørnevatn Line to Kirkenes for processing and shipping. The ore was discovered in 1866, but it was not until the 1900s that new technology made it commercially viable. Sydvaranger was established in 1906 by Christian Anker and Nils Persson and had Sweden's Metallurgiska as the majority owner. Production started in 1910 and capacity was increased in 1913.

Cross section of a mango tree The distribution of vascular plant roots within soil depends on plant form, the spatial and temporal availability of water and nutrients, and the physical properties of the soil. The deepest roots are generally found in deserts and temperate coniferous forests; the shallowest in tundra, boreal forest and temperate grasslands. The deepest observed living root, at least 60 metres below the ground surface, was observed during the excavation of an open-pit mine in Arizona, USA. Some roots can grow as deep as the tree is high.

The mine is located within what used to be a small equatorial mountain glacier. Steepening of slopes related to mining activities, as well as earthquakes and frequent heavy rainfall, have resulted in landslides within the open pit mine. While landscape reclamation projects have begun at the mine, environmental groups and local citizens are concerned with the potential for copper contamination and acid mine drainage from the mine tailings into surrounding river systems, land surfaces, and groundwater. Freeport argues that its actions meet industry standards and have been approved by the requisite authorities.

From Mapping to Mixing: Political Recognition of Expertise from the Allotment System to the Public Promotion of ManufactoriesIntroduction To Mining Once the rock was heated by fire it was quenched with water to break it. Fire-setting was one of the most effective rock breaking methods until 1867 when Alfred Nobel invented dynamite. Traditional mining operations have created some of the largest handmade features on Earth, such as the Big Hole open pit mine in South Africa, which is claimed to be the largest hole on Earth excavated by hand.

Sierra Legal launched legal action in Canadian federal courts to overturn the Department of Fisheries and Oceans regulatory approval (Ecojustice Canada 2007-03-30). They said that the joint federal-Alberta regulatory panel "failed to do its job" when it gave conditional approval to the $7 billion Kearl open-pit mine. They argued that a full environmental review must take place before the federal government decides whether the project should proceed. After a joint federal- provincial panel reviewed and upheld the original decision, a key water permit was reinstated, pending approval from Imperial's board of directors.

Sulfuric acid is produced at the open-pit mine when water, such as rain, snow melt or groundwater, interacts with the waste rock. This sulfuric acid leaches contaminants from surrounding rock, such as arsenic, copper, nickel, zinc, chromium, aluminum and iron. This acid rock drainage ARD, with a low pH, and high concentrations of dissolved sulfate and metals, flows into the surrounding watershed and has adverse effects on water quality through deposition of metal-rich precipitates, which cascade through the ecosystem affecting algae, insect, and fish. The site is unvegetated and is susceptible to erosion due to several long steep slopes.

After 1920, Rhyolite and its ruins became a tourist attraction and a setting for motion pictures. Most of its buildings crumbled, were salvaged for building materials, or were moved to nearby Beatty or other towns, although the railway depot and a house made chiefly of empty bottles were repaired and preserved. From 1988 to 1998, three companies operated a profitable open-pit mine at the base of Ladd Mountain, about south of Rhyolite. The Goldwell Open Air Museum lies on private property just south of the ghost town, which is on property overseen by the Bureau of Land Management.

The persistent uranium price slump has brought lower revenues for Niger's uranium sector, although uranium still provides 72% of national export proceeds. The nation enjoyed substantial export earnings and rapid economic growth during the 1960s and 1970s after the opening of two large uranium mines near the northern town of Arlit. When the uranium-led boom ended in the early 1980s, however, the economy stagnated and new investment since then has been limited. Niger's two uranium mines (SOMAIR's open pit mine and COMINAK's underground mine) are owned by a French- led consortium and operated by French interests.

In February 2011, an environmental impact survey found a total of 143 species from 70 genera were recorded, most of which were widespread and common in the region. The survey also discovered 3 new previously unknown species. One of these species, now known as Atriplex yeelirrie, was declared threatened and has a highly restricted distribution, only found in two known locations, approximately 30 km apart. The north western population (of an estimated 84,510 indivduals) is located on ground that coincides with the central part of the proposed open pit mine.

Seeds are spread by cattle and other animals, which consume the seed pods and spread the seeds in their droppings.Lalith Gunasekera, Invasive Plants: A guide to the identification of the most invasive plants of Sri Lanka, Colombo 2009, pp. 101-102. Its roots are able to grow to a great depth in search of water: in 1960, they were discovered at a depth of 53 meters (175 feet) at an open-pit mine near Tucson, Arizona, putting them among the deepest known roots. The tree is said to have been introduced to Sri Lanka in the 19th century, where it is now known as vanni-andara, or katu andara in Sinhala.

Located near Salt Lake City, Utah, the Bingham Canyon Mine (Kennecott Utah Copper/Rio Tinto) is one of the largest open pit mine in the world and one of the world's largest copper producers. In April 2013, the mine experienced a catastrophic landslide that halted much of the mine's operations. As part of the cleanup efforts and to improve safety, mine administrators turned to remote control excavator, dozers and teleremote blast hole drills to perform work on the highly unstable terrain areas. Robotic technology helped Kennecott to reduce the steeper, more dangerous areas of the slide to allow manned vehicles access for cleanup efforts.

It is an open pit mine located near the town of Brownsweg. Golden Star Resources and Cambior had conducted the exploration and development work to bring the mine into commercial production in 2004. Iamgold acquired Cambior in 2006 while Golden Star sold its stake to Euro Ressources S.A. which Iamgold acquired in 2008. With 2.9 million ounces in proved and probable reserves as of 2020 (with additional reserves in the neighboring Saramacca expansion property and potential for zinc extraction), the mine has produced approximately 300,000 ounces of gold per year. In the Abitibi Municipality of Quebec, Iamgold acquired the Doyon Division mining property with its 2006 acquisition of Cambior.

In 2017, with a preliminary economic assessment estimating a 21-year mine life producing an average of 302,000 ounces of gold annually at an all-in sustaining cost of $686/oz, Iamgold sold a 30% stake in Côté Gold to Sumitomo Metal Mining. A feasibility study completed the next year estimated the open pit mine would require an initial capital cost of $1.15 billion and adjusted the estimated production numbers to 367,000 ounces of gold annually over 16 year life span. Meanwhile, feasibility studies for the Senegalese Boto Gold project estimated a potential for approximately 160,000 ounces of gold annually over 11-year mine life.

Most coal from British Columbia mines is exported on the international markets through coal ports near Vancouver or Prince Rupert. Major coals mine fields in the province include a field in the Kootenay Mountains in southeastern B.C., and Peace coalfields in northeastern B.C. British Columbia's largest producing coal field is in Elk Valley (British Columbia), which is located in the Kootenay Mountains, about 60 kilometres from the borders of Montana and Alberta. It has had operational coal mines for over a century. By 2020, Teck Resources owned all five coal mines in that region including Elkford Operations, an open pit mine just east of the Alberta border with British Columbia.

The world's largest asbestos mine, the Jeffrey Mine in Asbestos, Quebec had its beginnings in the 1878 when a local farmer W. H. Jeffrey began to mine the substance there. Original mining methods were primitive and involved blasting, the use of chisels to remove the mineral from the rock by hand and a crane powered by one horse. By 1895, 2300 tons of asbestos were being removed from the open pit mine per year. The mine was purchased by the Johns-Manville Company of the US in 1918 and has since become the largest asbestos mine in the world, over two kilometres in diameter and 350 metres deep.

The delegation met with Cynthia Carroll, CEO of Anglo American, claiming that the Bristol Bay watershed is no place for an open-pit mine. Multiple UK jewelers pledged not to buy gold from the Pebble mine if it is built, joining several American jewellery retailers and manufacturers who had done the same in 2008. The Natural Resource Defense Council (NRDC) and other well known groups and figures (like movie star, Robert Redford) have opposed the construction of the mine. In an effort to stop or pause the construction of the mine, the NRDC has created a petition that now has more than a million signatures.

A coal phase-out for Germany is implied in Germany's Climate Action Plan 2050, environment minister Barbara Hendricks said in an interview on 21November 2016. "If you read the Climate Action Plan carefully, you will find that the exit from coal-fired power generation is the immanent consequence of the energy sector target.... By 2030... half of the coal-fired power production must have ended, compared to 2014", she said. Plans to cut down the ancient Hambach Forest to extend the Hambach open pit mine in 2018 have resulted in massive protests. On 5 Oct 2018 a German court ruled against the further destruction of the forest for mining purposes.

It was assumed that participants in the Fridays for Future demonstration would also participate in actions of Ende Gelände. In advance, the police had warned of an instrumentalization of Fridays for Future by Ende Gelände 2019, which was seen by many as a "deliberate attempt to divide the movement," but instead it led to public statements of solidarization of Fridays for Future with Ende Gelände, stating that civil disobedience was a legitimate form of protest to save the future, but, in the demonstration on June 22, 2019 in Hochneukirch/Jüchen in the direct neighbourhood of the open-pit mine, that Fridays for Future would remain on the legal side.

When Jack and Wolf are accused of mischievous "hitchhiking" and "trouble-making" by a highway police officer, they are sent by the court to a camp/school for troubled youths run by evangelist Robert "Sunlight" Gardner/Osmond. It is located in eastern Indiana and parallels a terrible open pit mine in the Territories where slaves are used to gather radioactive ore for Morgan. Jack and Wolf are held as wards of the state in Sunlight Gardener's School for one month, escaping after Wolf transforms and brutally kills a number of students in the school. Sunlight Gardener escapes during the attack and Wolf is shot four times by Sonny Singer (a prefect at the school) and dies of his injuries.

Starting from the generation station in Labrador, the power lines span a distance of over the Churchill River gorge and run generally south-southwest for as three side-by- side power lines in a cleared right-of-way with a width of . As they head southwest through boreal forest, the lines generally traverse flat, smooth rolling hills. After the lines cross the Quebec-Labrador border, also known as the Hydro-Québec point of delivery, the direction of the lines becomes due south, and they head to the Montagnais Substation, a substation accessible only by an airport adjacent to it. A lone 735 kV line stems off from the substation, heading to an open pit mine the northwest.

All that is left today are the Pit Heap, now a park, and the entrance to the mine shaft, now in the Bothal Court estate. Coinciding with the coal industry, there was also a brickworks in Pegswood, which has since closed down. Though the original colliery closed, mining was practised until quite recently: as late as 1997, mining company The Banks Group opened up a open-pit mine at Pegswood Moor, from which they extracted some 1.4 million tons of coal, with the help of a 236-ton face shovel made by Orenstein & Koppel. Also reaped was 84,000 tons of fire clay, a kind of high temperature resistant clay often found between coal layers.

Artists participating in the event included Brass Riot, Culcha Candela, , Moop Mama, Ruslana Lyzhychko, KingzCorner, Leo Holldack and Davide Martello. Among the protesters were Rezo and Anton Hofreiter. In parallel to this event, a group of Ende Gelände 2019 activists started protests at the nearby Garzweiler II open-pit lignite mine, blocking various mining infrastructure over the weekend. FFFD had recently declared its solidarity with this movement, stating that under the circumstances civil disobedience would be a legitimate form of protest to save the future, but, organizing another demonstration on 22 June 2019 in Hochneukirch/Jüchen in the direct neighborhood of the open-pit mine, that Fridays for Future would remain on the legal side.

General Motors developed the Titan in response to the need for more efficient haul trucks by open pit mine operators. GM believed that a general decrease in mineral ore quality combined with a projected need to mine tar shale and tar sands would increase the quantity of ore hauled by surface mine operators' trucks, worldwide. The Titan was the largest in the Terex 33 series of off-road haul trucks, which also included the 33-03, 33-05, 33-07, 33-09, 33-11 and the 33-15. The 33-19 and the 33-15 both used diesel/AC electric powertrains, while the other, smaller members of the 33 series of haul trucks used mechanical powertrains.

Huge residential tracts were developed through the center of the valley, and within ten years, the entire area had been converted from farmland into sprawling bedroom communities to Salt Lake City. West Valley City was created from the merger of the three unincorporated cities of Granger, Hunter, and Redwood (including Chesterfield) in 1980. But not every area of the county saw growth. The former mining towns related to Bingham Canyon were abandoned in the 1960s and 1970s to make way for expansion of the open-pit mine. The city of Bingham Canyon was completely torn down and swallowed up in the mine by 1972, and the dismantling of Lark in 1980 completed the process.

Lake Paljuvi, or Paljuvi-Viš Reservoir, was built in 1988 when the Kladnica river was dammed. Within the Kolubara river watershed, it was created specifically for the protection of the open-pit mine Zapadno Polje, part of the vast Kolubara mines ("RB Kolubara") as the Kolubara is notoriously flooding river, so as for the nearby thermal power station. Projected to receive the surplus of water, the lake is connected to the small Vraničina river by the drainage tunnel. The reservoir was mostly kept almost empty, so that it would be ready to receive the water and in the next 25 years there was never an overspill of the water over the dam, as the drainage tunnel was always operational.

Kajaran copper-molybdenum open-pit mine in southern Armenia is operated by the Zangezur Copper and Molybdenum Combine and is 75% owned by the German CRONIMET company The Teghut Mine (opened in December 2014) contains a copper and molybdenum deposit valued at over US$15 billion and has destroyed over 350 acres of Armenia's little-remaining forested land. The operator of the mine, Vallex Group, will pay only about 10% of revenues in taxes. The mineral industry is one of the main sectors of the Armenian economy and in 2017 accounted for 30.1% of its exports. Armenia is a major producer of molybdenum, which is used in some high-quality forms of steel, and other alloys.

Only 10% of the forest area remains. RWE plans to clear half of the remaining area of the forest between around 2018 and 2020; this plan was met with massive protests in autumn 2018, and was temporarily stopped in October 2018 by the supreme administrative court of North Rhine–Westphalia (Oberverwaltungsgericht für das Land Nordrhein-Westfalen). Begun in 1978, the mine's operation area currently (as of end of 2017) has a size of 43,8 km2, with the total area designated for mining having a size of 85 km2. It is the deepest open pit mine with respect to sea level: the bottom of the pit with up to from the surface is below sea level, the deepest artificially made point in North Rhine–Westphalia.

As Toronto’s last remaining landfill site, Keele Valley, neared capacity during the 1990s, it was found that no other municipality in Southern Ontario was willing to accept the garbage, but there was also no political support for a change to incineration. A deal was eventually made to ship Toronto's garbage to the Adams Mine, an abandoned open pit mine in Northern Ontario, once the Keele Valley site closed. But controversy grew into vehement objection as the time neared, and eventually the agreement was canceled. By the time the Keele Valley site closed at the end of 2002, the city had made a new deal, to ship its garbage by truck to Carleton Farms Landfill in Sumpter Township, Michigan, United States.

Pit Power Tower concept in Bingham Canyon mine The Pit Power TowerPit Power Tower - Alternative Energy News Feb 2009Pit Power Tower US Patent combines a solar power tower and an aero-electric power towerEnergy tower in a decommissioned open pit mine. Traditional solar power towers are constrained in size by the height of the tower and closer heliostats blocking the line of sight of outer heliostats to the receiver. The use of the pit mine's "stadium seating" helps overcome the blocking constraint. As solar power towers commonly use steam to drive the turbines, and water tends to be scarce in regions with high solar energy, another advantage of open pits is that they tend to collect water, having been dug below the water table.

The project was originally for the exploration and development of beryllium and uranium, both of which are found in the mountain. Texas Rare Earth Resources picked up the project in 2011 with the re-logging and re-analyzing of the previous 82,000 feet (approximately 24,993 meters) of drilling. A 1990 study by the Texas Bureau of Geology estimated the rare-earth deposits in the mountain to be 1.6 billion metric tonnes. The Round Top Project plans to extract the heavy rare- earth elements through an open-pit mine, crushing the ore and using a heap leaching process to extract the elements. The project cost is approximately $290 million with an estimated $8 billion in projected revenue over 20 years of mining.

The Québec Cartier Mining Company opened the Lake Jeannine iron mine to the southwest of Fire Lake in 1961, near the company built town of Gagnon. The company made investments in the 1970s at Mont-Wright, Fermont and Fire Lake. The open pit mine near Fire Lake was exploited by Sidbec-Normines, a private-public consortium, between 1977 and 1984. Before the work began, in 1971–1977 facilities were built around the hamlet of Fire Lake, and a road was built that connected it to the town of Gagnon, to the southwest. In all 54 million tonnes of iron was extracted from Fire Lake, transported in the form of iron and silica pellets to the Port Cartier plant, then mostly shipped to Europe.

In reference to his experience in Chile, Guevara also writes: "The most important effort that needs to be done is to get rid of the uncomfortable 'Yankee-friend'. It is especially at this moment an immense task, because of the great amount of dollars they have invested here and the convenience of using economical pressure whenever they believe their interests are being threatened." Unable to get a boat to Easter Island as they intended, they headed north, where Guevara's political consciousness began to stir as he and Granado moved into mining country.Che Guevara: Symbol of Struggle, by Tony Saunois, CWI, 2005, pg 9 They visited Chuquicamata copper mine, the world's largest open-pit mine and the primary source of Chile's wealth.

Pebble is the largest known undeveloped copper ore body in the world, measured by either the amount of contained metal or the amount of ore. Northern Dynasty estimated that Pebble contains over $300 billion worth of recoverable metals at early 2010 prices. A report released by Northern Dynasty in 2011 predicted profits for mine owners from a large-scale open-pit mine at Pebble, given appropriate assumptions about construction costs ($4.7 billion), scale (200,000 tons per day), lifetime (45 years), metal prices over that lifetime (2011 prices) and the mine design plan. The study assumes a slurry pipeline will deliver ore concentrate from the mine to a new port on Cook Inlet, and that trucks will haul ore concentrates to Cook Inlet.

Companhia Brasileira de Metalurgia e Mineração (Portuguese for Brazilian Metallurgy and Mining Company), or CBMM for short, is a Brazilian company that specializes in the processing and technology of niobium, extracted from its pyrochlore mine near the city of Araxá, in the Brazilian state of Minas Gerais. CBMM is by far the world's largest producer of niobium metal and its alloys, providing over 80% of the world's supply. Like the other producers of this metal, the company does not sell raw niobium ore, only ferroniobium, other niobium alloys and oxides, and the pure metal, all produced in its facilities next to the open-pit mine. As of 2016, CBMM produces 90,000 tonnes of ferroniobium equivalent per year, which is slated to be increased to 150,000 tonnes/year.

The plaintiffs tried to stop the relocation of the A4, which was deemed necessary for the planned extension of the open pit mine and justified this, inter alia, with feared noise pollution as well as the possible threat to the protected Bechstein bat and other species. In 2009, the construction of the new section of motorway began, in September 2014, it was opened to traffic. Since 2008, there have increasing complaints about possible damage to the hill in the Elsdorf- Heppendorf area; since the burden of proof lies with the complainants, it is difficult to prove the mining operator guilty. The newly formed brown coal committee therefore decided on 16 April 2010, to set up the Bergschaden Braunkohle NRW reclamation service for damage victims in the Rhenish lignite mining area.

The Attawapiskat kimberlite field is a field of kimberlite pipes in the Canadian Shield located astride the Attawapiskat River on Attawapiskat First Nation land. It is thought to have formed about 180 million years ago in the Jurassic period when the North American Plate moved westward over a centre of upwelling magma called the New England hotspot, also referred to as the Great Meteor hotspot. The area is composed of 18 kimberlite pipes of the Attawapiskat kimberlite field, 16 of which are diamondiferous; the Victor Mine sits on top of the Victor pipe and mines from Victor Main and Victor Southwest which have appeared close enough to the surface to be used in an open-pit mine. The Victor Kimberlite is a composition of pyroclastic crater facies and hypabyssal facies, and is considered to have a highly variable diamond grade.

The Pre- Feasibility study recommended underground mining, a standard gravity/flotation mill and concluded that a profit of $40 per ton would be realized. The first feasibility study expanded on the pre-feasibility study and described three possible options, two of which involved variations on a portable 500 metric ton/day mill and underground mining, and the third option involved open pit mining, selective underground mining and a 5,000 metric ton/day mill. All scenarios were considered economically viable but the third option of an open pit mine and large mill was considered to have the largest possible return to shareholders and was the recommended option. The second feasibility study was produced two months after the first and recommended only a modified sub-level retreat mining methodology with no mention of the open pit mining option described in the first feasibility study.

In 2015 he performed at the sites of the January 2015 Île-de-France attacks. Later that year in the aftermath of the November 2015 Paris attacks, on 14 November 2015, Martello rode his grand piano by bike to the Bataclan theatre (the venue where 89 people were killed in a terror attack) and started playing "Imagine" from John Lennon in tribute to the victims of the Paris attacks for a crowd gathered outside the hall. On 6 October 2018 Martello performed at the "" demonstration against the cutting of the Hambach Forest to extend the Hambach open pit mine in Germany. In March 2019, on the way to play at a pier in San Francisco, Martello wrecked his piano on a hill on Bay Street, but was able to mend it sufficiently to play as planned.

There have been copper prospects operating on Red Mountain 2445 m (8022 ft), the highest in the range, and on Poison Mountain 2264 m (7428 ft), just south Red, is located where the spine of the Shulaps Range intersects with that of the Camelsfoot, at the apex of the Yalakom valley which runs SE towards Lillooet from this point. Poison Mountain's name comes from the toxic leaching of its orebodies into local streams (and rumours of mercury in the copper ore) while Red's comes from the colour of its cuprous earth. Red's flanks show ziggurat-like scars that are evidence of the scale of ore-sampling that at one time was underway. There are projected open-pit mine and smelter plans for the Poison Mountain-Red Mountain orebody, using power from the also projected Hat Creek lignite deposits nearby on the other side of the Fraser.

It is a conventional open-pit mine with an on-site mill where doré bars are produced from ore that is ground, dissolved into a pyrite flotation, sent through a carbon in leach system and collected by electrowinning. The mine opened in 1997 and since ownership was transferred to Centerra in 2002, the mine has produced approximately 500,000 ounces of gold per year, except for 2012 due to a pit wall collapse (from excessive amounts of ice following winter storms) which closed operations for half the year. In addition to the numerous accidents that occurred prior to Centerra, the mine has been the subject to numerous controversies, including health and safety concerns, impacts on the natural environment from excavating glacial material and disposal of waste, and political debate due to its prominence in the Kyrgyz Republic. The Öksüt gold mine is located in the Kayseri Province of Turkey.

The world's longest ore tramway, between Boliden's mine in Kristineberg and Boliden became operational in 1943. The ore tramway was 96 km long and by the time it was shut down, 44 years later, it had transported 12 million tonnes of concentrate. Operations started at the Aitik mine, outside Gällivare, in 1968. This open pit mine would develop, over the years, into one of Europe's biggest copper mines. During its first year of operations, it produced approximately 9,000 tonnes of copper, 160 kg of gold and 7 tonnes of silver. The company grew during the first few years of the 1970s thanks to a joint venture with the German company, Preussag. This led to the expansion of Boliden's lead smelting and refining capacity, and in 1976, Boliden launched a Kaldo type furnace, for processing metals. 1976 also saw Boliden launch the first flash smelting furnace for lead, applying Kaldo technology, at Rönnskär.

An open pit mine may be modeled as a set of blocks of material which may be removed by mining it once all the blocks directly above it have been removed. A block has a total value, equal to the value of the minerals that can be extracted from it minus the cost of removal and extraction; in some cases, a block has no extraction value but must still be removed to reach other blocks, giving it a negative value. One may define an acyclic network that has as its vertices the blocks of a mine, with an edge from each block to the blocks above it that must be removed earlier than it. The weight of each vertex in this network is the total value of its block, and the most profitable plan for mining can be determined by finding a maximum weight closure, and then forming a topological ordering of the blocks in this closure..

Engro Energy Limited (formerly Engro Powergen Limited) The story of Engro Energy goes back to 2008, when a fully owned subsidiary was incorporated by conglomerate Engro Corporation to develop power projects in Pakistan and beyond. Their first intervention in the energy sphere was launched in the form of Engro Powergen Qadirpur Limited which owns and operates a cutting edge 217 MW power plant in Qadirpur, Dharki and runs on permeate gas which was previously being flared. This unique aspect makes the Engro Powergen Qadirpur plant one of the few green power plants in Pakistan earning carbon credits. Moving further in its efforts to improve energy efficiency and ecosystem in the country, Engro Energy formed the Sindh Engro Coal Mining Company in collaboration with its partners to unearth and mine one of the world’s largest lignite coal reserves in Thar – achieving a first for the country in terms of becoming one of the only private sector entity with the engineering capability, capacity and expertise to operate and optimize an open-pit mine.

Marie, where longtime incumbent MP Tony Martin was defeated despite that election's historic increase in NDP support nationwide; in the 2015 election, however, a resurgence of Liberal support under Justin Trudeau resulted in the Liberals regaining all of the region's seats except Timmins—James Bay and Algoma—Manitoulin—Kapuskasing, where the NDP incumbents were successfully re- elected. Major political issues in recent years have included the economic health of the region, the extension of Highway 400 from Parry Sound to Sudbury, issues pertaining to the quality and availability of health care services, mining development in the Ring of Fire region around McFaulds Lake, the closure of Ontario Northland, the Algo Centre Mall roof collapse of 2012, and a controversial but now-defunct plan to ship Toronto's garbage to the Adams Mine, an abandoned open pit mine in Kirkland Lake. In the redistribution of provincial electoral districts before the 2007 election, the province retained the existing electoral district boundaries in Northern Ontario, rather than adjusting them to correspond to federal electoral district boundaries as was done in the southern part of the province. Without this change, the region would have lost one Member of Provincial Parliament.
