摘　　要：对云南某地高含泥高碱性脉石矿物的氧化铜矿石,采用氨浸-萃取-电积的工艺来处理。小型试验研究考察了机械搅拌浸出的各种影响因素,拟定按常温常压的方式来浸出,以便产业化应用。试验结果表明采用两段浸出的工艺比单段浸出总铜浸出率提高了7.48%。A place in Yunnan containing high amount of mud and high-alkaline gangue mineral oxide copper ore,the use of ammonia baptist-extraction-electrowinning process to deal with it.Experimental study of small-scale study of the mechanical agitation leaching of a variety of factors,drawn up by way of normal temperature and pressure leaching,to industrial applications.Test results show that the leaching process using two single-stage leaching than the total copper leaching rate increased 7.48%.
