摘　　要：某浸钴渣中铜品位1.31%、钴品位0.20%,根据其中铜、钴的赋存状态,采用磨矿-一粗一扫两精浮选工艺回收浸钴渣中铜和钴,闭路试验可获得产率6.63%、铜品位16.16%、钴品位2.06%、铜回收率80.56%、钴回收率68.29%的铜钴混合精矿,实现了浸钴渣中铜、钴资源的高效富集回收。For a cobalt leaching residue grading 1.31% Cu and 0.20% Co,a flowsheet consisting of grinding and a flotation process of one stage of roughing,one stage of scavenging and two stages of cleaning was proposed based on the occurrence of copper and cobalt therein.A closed-circuit test employing this processing technique can result in a bulk copper-cobalt concentrate grading 16.16% Cu and 2.06% Co with recoveries of 80.56% Cu and 68.29% Co,with the yield of 6.63%.It is concluded that with this approach,copper and cobalt resources in the cobalt leaching residue can be enriched and recovered efficiently.
