A secondary copper ore in Xizang is mixed copper-lead ore,with copper primarily in the form of chalcocite and  lead  in the form of galena.Experimental exploration revealed that separating copper and  lead  in the result-ing concentrate from this ore is challenging.Therefore,a flotation process prioritizing copper separation followed by lead separation was determined to be optimal.In the experimental process,inhibitors YS02 and YS04 effectively suppressed galena,while the highly selective collector BS09 yielded copper concentrates with qualified lead grades.Ultimately,under the conditions of a grinding fineness of -0.074 mm accounting for 65 %,a copper separation process of once roughing and three times scavenging,and a lead separation process of once roughing,three times scavenging,and three times cleaning,the experiment achieved a copper grade of 24.63 % and a copper recovery rate of 81.05 % for copper concentrates,as well as a lead grade of 45.59 % and a lead recovery rate of 81.32 % for lead concentrates.The experimental indicators are considered ideal.
