platinum mine tailings dam

Anglo American Platinum Mogalakwena Mine Tailings Dam

2020-8-3  The tailings dam on Blinkwater was built to support the Mogalakwena Mine, the world’s largest open-cast platinum mine, which produces 450,000 ounces of platinum yearly worth $323 million. The mine produces 70 million tons of waste rock and tailings annually. The waste tailings dam has contributed to land loss and degradation, groundwater pollution, and health hazards [4].

Managing tailings safely – Anglo American Platinum

Tailings will naturally separate so that coarse material settles closest to the starter dam, while liquid and fine material settles furthest away. As the level of the materials rises, the crest of the dam is raised “upstream”, using the support of the previous dam raise and the tailings beach area. DOWNSTREAM.
