摘　　要：试验研究结果表明,该低品位含金硫精矿用硫脲法浸金在技术上是可行的。当试样磨至-0.044mm90%,经稀硫酸预浸后进行硫脲浸出,硫脲用量为5g/t、浸出时间为6h时,金的浸出率达81.09%。The experiment on leaching low -grade gold from pyrite with thiourea indicates that leaching gold from pyrite with thiourea is technically feasible and effective. When the sulphur concentrate is grinded to 90% minus 0.044mm,pretreated with diluted sulphuric acid,thiourea dosage of 5g/t, and leaching time of 6h, gold leaching rate is 81.09%.
