| Abstract: | 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%. |
