Comprehensive Recovery and Utilization of a Lead-zinc Tailing Containing Cadmium in Guangxi

This is an article in the field of mineral processing engineering. In this article, the recovery and utilization under the condition of origin potential of galena and sphalerite from a lead-zinc tailings containing cadmium in Guangxi was studied. Research indicates S19 exhibits satisfactory recovery for galena, while CZ008 as a novel collector for zinc flotation can effectively recover activated-sphalerite. Flotation tailings may serve as a silicate excipient for cement after gravity concentration in cleaning table and desulfurization. The wastewater produced by the process can be recycled without treatment and will not affect the recovery index.
