Abstract:This testwork was carried out to solve the problems that flotation indexes were lower and separation of copper zinc was difficult during the course of production on the site. The self-research collector TL-1 for copper and depressor BK510 for pyrite were applied and the following test indexes were gained: Cu Concentrate was 22.86% Cu and 3.96% Zn at a recovery of 93.68%; Zn concentrate was 48.77% Zn and 0.092% Cu at a recovery of 94.72%. The results indicated that the collector TL-1 had good selectivity and collecting capability for copper minerals and BK510 had effective depressing action for pyrite.
