Recovery of Copper from Copper Smelter Slag by Flotation

Abstract:

The recovery of copper from copper smelter slag utilizing flotation has been studied. A copper smelter slag from the Wang Jiaqiao smelter in Yunnan Province of china, containing 2.76% Cu, 44.41% Fe, 2.34% Zn and 18.4g/t Ag and so on, has been used .The effective factors such as grinding fineness, pH, and the dosage and type of collector were examined. Under the flotation condition of grinding fineness (90%-74μm), rougher pH 6, XT-53(80 g/t), and 2^# oil (30g/t) , copper grade of 23.55 %, recovery of 85.61% was obtained. Besides, silver get a recovery of 76.2% and grade of 143.07g/t as associated metals.
