摘　　要：含砷硫铜金精矿加入助剂经低温焙烧预处理后 ,在添加活化剂的条件下氰化 ,金的氰化浸出率从直接氰化或焙砂氰化的 18%～ 35 %提高到 80 %～ 90 %以上 ,浸出速度也有提高。After having been roasted adding a promoter at low temperature,the gold concentrate containing arsenic,sulphur and copper was cyanided under adding activator. The results of cyanidation showed that the gold recoveries were increased from 18%～35% for directly conventional cyanidation or calcine cyanidation to 80%～90% or higher and cyanydation rate was also improved .
