Abstract: Experimental leaching studies conducted on a clay oxide copper from Yunnan,combination of different size fractions of the ore may dip the performance difference of ore grading dealt with separately.+0.074mm at room temperature agitation leaching with ED-1,-0.074mm heated by 80℃ agitation leaching.By agitation leaching experiments to determine the optimum leaching parameters,consolidated copper leaching rate reached 81.93% under optimal conditions,tons of copper integrated acid consumption 13.86t,copper leaching rate has increased dramatically over the existing leaching process at room temperature.
