Sulphide precipitation – Mine Closure

WebA key step in the reactions of all the sulfide minerals is that they release iron as ferrous ion (Fe2+). Oxygen present in the water can then oxidize Fe2+ back to Fe3+: (8) 2 Fe 2 + + 1 2 O 2 + 2 H + → 2 Fe 3 + + H 2 O. This Fe3+ can again react with the mineral surface. Hence, the presence of oxygen greatly accelerates the rates of reactions ...
