Jan 01, 2004· Thealkaline oxidationofrefractory goldconcentrates containing arsenopyrite and pyrite at ambient temperatures and pressures has been found to be accompanied by the simultaneous dissolution ofgoldwithout the addition of cyanide. A detailed study has been made of the kinetics of the oxidation of the pure minerals and of several concentrates. Thereactionproducts of theoxidationofarsenic…
Theoxidationofrefractory goldconcentrates containing arsenopyrite and pyrite and the simultaneous dissolution ofgoldin aeratedalkalinesolutions at ambient temperatures and pressures without the addition of cyanide has been studied. It involves the following aspects: the chemistry of the oxidation of pure arsenopyrite and pyrite minerals in aeratedalkalinesolutions; the kinetics of oxidation of arsenopyrite and the simultaneous dissolution ofgold…
