Reclaiming Copper Resource from Copper Slag:Beneficiation Test Research and Production Practice
A process mineralogy study and mineral processing tests were conducted for a copper slag with Cu grade of 0.81％,and a beneficiation flowsheet for recovering copper resource and its technical parameters were determined.With Z-200 and 2# oil respectively as collector and frother,the slag was processed after being milled to a fineness of-0.038 mm 85％,and a high-grade copper concentrate with Cu grade of 26.40％was collected by fast preferential floatation,while a low-grade copper concentrate with Cu grade of 3.58％was obtained from a subsequent flotation process consisting of one stage of roughing,two stages of scavenging and two stages of cleaning,resulting in the total copper concentrate grading 13.03％Cu at 76.47％recovery.This copper-recovering technique has been successfully applied in commercial practice,showing that the comprehensive utilization of Cu metal resource in a copper slag can be actualized.
