Characterizing gold in refractory sulfide gold ores and , - Know More
Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite, where it occurs in both the chemically bonded state and as nano-size grains of metallic gold During roasting or pressure oxidation, the sulfide matrix is destroyed and essentially all the gold is converted to the metallic form The liberated gold is readily dissolved in conventional cyanide media ....
