-Volmer relation were delineated, and kinetic equations with respect to ferric ions for each sulfide mineral were obtained. The kinetic equations show that when the concentration of ferric ion... constants of reactions (3)-(6) and reverse reactions of (3)-(6). Owning to that there are no external sulfide mineral mental ions exist in solution and the reverse reactions of (3)-(6) can be ignored......
