An experimental study was carried out on comprehensive recovery process for the gold-cobalt polymetallic copper ore in Bolivia. A flow sheet of Cu-preferential flotation followed by bulk Au-Co-Bi flotation was adopted, with OL-ⅡA as a Cu collector and OL-TL as a depressant. The Cu-preferential flotation process consisting of one stage of roughing, two cleaning and one scavenging produced a copper concentrate grading 30.00% Cu at 94.56% recovery, indicating separation between copper and arsenopyrite actualized by low-alkalinity flotation. Then, the obtained tailings were subjected to a bulk Au-Co-Bi flotation consisting of one stage of roughing, one cleaning and one scavenging, resulting in a Au-Co-Bi concentrate grading 19.50 g/t Au, 1.58% Co and 1.80% Bi, with corresponding recoveries of 92.22% Au, 96.33% Co and 58.87% Bi. It is concluded that the comprehensive recovery of metallic resources can be actualized from this gold-cobalt polymetallic ore.
