摘要
对某含铜金矿石进行常规氰化、氨浸—氰化、酸浸—氰化、浮选—氰化等工艺处理,金回收率均较低,且氰化钠耗量高;而采用硫代硫酸盐法对该金矿石进行浸出,金浸出率高达92.64%。
Conventional cyanidation, ammonia leaching-cyanidation, acid leaching-yanidation, and flotation-cyani- dation for copper-containing gold ores all obtain a fairly low recovery rate, and the consumption of sodium cyanide is high. However,with the thiosulfate process for the gold leaching, the leaching rate is high up to 92.64 %.
