It is known that oxide minerals of useful components are presented by complex oxidized forms and are not practically floatable. The paper gives the opportunity for complex oxide lead-zinc ore to be prepared effectively to flotation beneficiation based on pyrosulphidization of oxide minerals while roasting. The process of roasting is held in the atmosphere of overheated steam using sub-quality ...
