Experimental study on gold and silver recovery associated with a certain copper mine
The associated gold and silver contents of a copper mine in Jiangxi Province are 0.10 g/t and 3.45 g/t respectively,which has certain comprehensive utilization value.The results show that the comprehensive recovery index of Cu,Au and Ag is better when the collector is ammonium butyl black powder,the grinding fineness is-0.074 mm accounting for 75%,and the flotation time is 5 min.On the basis of the condition test,the closed-circuit test is carried out,and the copper concentrate with Cu,Au and Ag grades of 8.57%,1.63 g/t and 83.6 g/t are obtained,with recoveries of 4.93%,5.03%and 4.64%relative to the raw ore,respectively.
