Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings. Characterization of potential acid mine generation in tailings led to an innovative process in which acid-generating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone. This creates pyrite-free neutral tailings acceptable for placement in the dyke and permanently avoids acid generation.

硫铁矿浮选分离和封装：尾矿坝同步修复系统

硫铁矿浮选分离和尾矿坝中的封装被提议为化学稳定尾矿的可行方法。尾矿中潜在的酸性矿山生成的表征导致了一种创新的方法，其中通过浮选将产酸黄铁矿与粗尾矿分离，并掺入到煤泥区中。这将产生无黄铁矿的中性尾矿，可以放置在堤中，并永久避免酸的产生。
