Abstract: On the basis of process mineralogy research result of a polymetallic sulphide ore in Qingyuan of Liaoning province, principle flowsheet of experimental study was made, according to the reasonable technology condition confirmed through experiment, closed circuit technological process experiment of one roughing one scavenging two cleaning operations copper and sulfur mixed flotation, one time weak magnetic lead sulfur separation, one time weak magnetic sulfur concentration, twice concentrate and float lead, one roughing one scavenging four times zinc cleaner flotation, middling order return were done, lead concentrate with Pb grade and recovery rate 60.79% and 90.83%,zinc concentrate with Zn grade and recovery rate 45.13% and 90.77%, sulfur concentrate with S grade and recovery rate 42.14% and 86.77 % were obtained, effect of efficient comprehensive recovery was reached.
