  • Oxidation of sulfides in waste rock piles

    Oxidation of sulfides in mining wastes produces high concentrations of sulfate, iron, and other metals and frequently also very low pH values. Compared with fine-grain mine tailings produced in ore treatment by flotation and other techniques, waste rock is just displaced material comprising large particles deposited into piles. In waste rock piles with high permeability and sulfide content, the ...
