  • The dangers of tailing dams on the planet

     · Most mines opt for the cheaper ''upstream method'' where the tailings themselves are piled up, with more tailings added to increase the height of the dam as mining operations continue. Dams built using the upstream method are more likely to collapse because, once dried, the tailings used to create the barrier become less dense and more sand-like, increasing the likelihood that it will erode and …
