|
|
Chambers, who heads the Montana-based Center for Science in Public Participation and advises mining communities, says companies should be forced to build tailings dams using other more expensive designs: downstream and centerline.

Vice Minister of Mining Fernando Benalcazar told Reuters the new rules will take effect in December and will prohibit the building of so-called tailings dams close to populated areas and ban certain designs that are considered less stable.
|
