Research advances of copper-sulphur separation in low alkaline medium

This article studies the advances of theoretical research advances on copper-sulphur separation. The research advances on collector agents for copper -sulphur separation in low alkaline medium are discussed based on the summarizing the traditional collector agents with strong selection on chalcopyrite. Then we compare the molecular structures of new collectors and traditional collectors by analyzing their respective mechanisms. The research advances of inhibitors for effective copper-sulphur separation in low alkaline medium are also outlined.
