Experimental Study on Copper Recovery by Flotation Method from Smelting Copper Slag
By analyzing the effects of grinding fineness,slurry pH value,collector dosage,and flotation process on flotation indicators,copper is recovered from smelting copper slag using flotation method.Experiments have shown that under optimal conditions,the grinding fineness is-325 mesh 80％,the slurry pH value is 7,and the collector dosage is 60 g/t.Using a flotation process of one coarse,two fine,and two sweeping,the closed-circuit flotation experiment can achieve a copper grade of 24.88％and a recovery rate of 95.48％in the concentrate,effectively achieving efficient recovery of copper resources from copper slag and significant economic benefits.
