Reclaiming Copper Resource from Copper Smelting Slag by Flotation Approach
Flotation technique was introduced to reclaim copper resource from a copper smelting slag with Cu grade of 2.70％.With sodium sulfide as the regulator,the scavenger middling was collected for flotation and its tailings were classified into a size range of+20 μm to return,together with the cleaning concentrate of middling,to the quick flotation stage.With this optimized flowsheet,a stage of scavenging can be dislodged and the mud content in the middling can be reduced.Finally,a closed-circuit test produced a copper concentrate grading 20.59％Cu at 91.75％recovery,and the tailings with Cu grade reduced to 0.26％.
