中文摘要: 针对某以银为主的多金属精矿,在前期氧化氨浸—氰化工艺小型试验基础上,进行了6 kg和30 t/d级的扩大试验。结果表明,氨浸渣脱铅率可达到93%,脱铅渣中Au氰化率可达到95%以上,当吨矿NaCN用量达到20 kg时,Ag氰化率也可达到97%以上,扩试结果与小试结果基本一致。根据工业试验相关经济核算,3年内可回收成本。
Abstract:Pilot-plant scale of 6 kg and 30 t/d experiments were carried out on the multi-metal silver concentrate based on the prior laboratory test result. The results show that deleading rate of ammonia leaching residue is up to 93%, cyaniding leaching rate of Au in deleading residue is above 95%, and 97% of Ag extraction rate is achieved with dosage of NaCN per ton residue of 20 kg. The results of pilot-plant scale experiments are in agreement with those of laboratory test. According to the economic accounting of industrial test, investment cost will be recovered within 3 years.
