摘　　要：研究了硫代硫酸盐法从焙烧后的含铜硫金精矿中回收金的工艺过程。研究表明，焙烧前金的回收率很低；焙烧后，常温下硫代硫酸盐浸出，既可获得较好的金浸出指标。This paper studies the process of the extraction of gold by ammoniacal thiosulfate leaching from the roasted copperbearing sulphureous gold concentrate.The experimental results show that the recovery ratio of the gold is quite low before the ore is roasted,however,through thiosulfate leaching at normal temperature after roasting,not only the better leaching rate can be obtained,but also the consumption of thiosulfate can be decreased.
