Abstract

Abstract : The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na2 S, CuSO4, and FeCl3 on sulphidizing flotation of copper oxide. The results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe 3+ inhibits the sulphidizing effect. Further analysis shows that Cu 2+ ions can reduce the surface potential, increase the S 2− adsorption, then generate more polysulfide, and therefore promote the sulphidizing flotation. However, Fe 3+ ions would increase the surface potential, reduce the S 2− adsorption, generate more sulfur element, and therefore inhibit the sulphidizing flotation.
