The gold and silver are recovered from certain sulfide concentrates containing gold and silver in Yunnan with fine grinding-cyanide leaching process,which is faced with low gold and silver recovery rates.To improve comprehensive resource utilization rates,experimental research on roasting-roasting slag washing-cyanide leaching process is carried out.The results show that under the optimal test conditions obtained,the gold and silver leaching rates are 89.51 % and 37.31 % respectively;the gold and silver leaching rates are increased by about 30 and 12 percentage points respectively compared with the previous fine grinding-cyanide leaching process;at the same time,magnetite concentrates with productivity 67.85 %,iron grade 62.60 % and iron recovery rate 96.69 % are obtained.The research results can provide beneficial reference for the comprehensive utilization of sulfide concentrates containing gold and silver.
