| Abstract: | Experimental study was conducted on flotation recovery of copper and molybdenum sulfide from flash furnace slag, with the influence of pulp pH value, grinding fineness and dosage of reagents on grade and recovery of copper and molybdenum concentrates investigated. The results show that, with processing parameters including pH=9, grinding fineness of -0.074 mm 90%, dosage of 200, 150, 180 and 120 g/t for Na2S, butyl xanthate, kerosene and pine oil, respectively, a closed-circuit flowsheet with one-roughing, two-scavenging and three-cleaning resulted in a copper concentrate with Cu grade of 34.80% at a recovery of 85.70% and a molybdenum concentrate with Mo grade of 1.90% at a recovery of 40.70%. |
