Abstract：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 mm85%, 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.
