Recovery of pyrite from copper tailings by flotation

2019-9-1  1. Introduction. The concentration of sulfide copper minerals by means of flotation generates large volumes of tailings. It is estimated that one hundred twenty-five tons of tailings are generated per one ton of produced copper, and its generation is on a continuous rise because of the decrease of the copper grades .On the one hand, the tailing is considered an
