摘　　要：研究了从石煤钒矿提钒尾渣中浸出金,考察了原料粒度、氰化钠用量、浸出时间、浸出温度、矿浆浓度等对金浸出率的影响,确定了最佳工艺参数。试验结果表明,在最佳工艺参数下,金浸出率为91.37%,浸出效果较好。The process for leaching gold from acid leaching tailings of a stone coal ore was investigated. The effects of granularity of raw materials, dosage of sodium cyanide, leaching time, leaching temperature and slurry density on leaching of gold were examined. Under the optimal process conditions,the leaching rate of gold is 91.37%.
