Abstract:Valuable metals were recovered from high sulfur and arsenic bearing refractory gold concentrates by two stage roasting, acid leaching, regrinding, and cyaniding. The results show that leaching rate of gold and silver is 90.86% and 56.95% respectively upon first-stage roasting at 550 ℃ for 60 min, second-stage roasting at 700 ℃ for 60 min, and cyanide leaching for 48 h under the conditions of acid leaching slag grinding to 0.038 mm accounting for 70% and dosage of sodium cyanide of 6 kg/t.
