  • Flotation to Recover Copper Minerals from a LowGrade

    Abstract: Depressants used in flotation can inhibit floatable gangue minerals to improve concentrate grade. In this paper, four different commonly used depressants were adopted in order to investigate the effect of depressants on chalcopyrite index and to investigate their inhibition effects on chalcopyrite flotation.The experimental results indie that, in the flotation system of natural pH
