  • Environmental Risks From Mine TailingsThoughtCo

    Aug 10 2018 · When rain falls on tailings it leaches away materials that can create water pollution for example lead arsenic and mercury. Sulfuric acid is sometimes produced when water interacts with tailings or it can be a by-product of ore processing. As a result highly acidic water leaks from the tailings and disrupts aquatic life downstream Also the recovery of silver minerals occurring in a lead zinc sulfide ore is efficiently accomplished using Flowsheet #2. The process consists of selective flotation to produce a mixed silver lead concentrate for maximum smelter return and a separate zinc concentrate. Over-grinding of silver minerals is detrimental to efficient flotation
