| Abstract: | With a copper-bearing pyrrhotite-serpentine (talc) ore from Anhui taken for research, effects of grinding fineness, type of collectors and depressant, as well as regrinding and re-separation of middlings on copper flotation were investigated. After milled to a grinding fineness of -0.074 mm 84%, the ore was treated with Z200 and butyl xanthate as a combined collector and dextrin as a depressant. The experiment adopting a flowsheet consisting of one stage of roughing, two stages of scavenging and three stages of cleaning, with the middlings reground for re-separation finally produced a copper concentrate grading 17.21% Cu with corresponding 86.30% recovery. As a result, the sliming problem of silicate gangue relating to this kind of ore can be effectively solved. |
