Introduction. Pyrite (FeS 2, iron disulfide), is the most abundant sulfide mineral and commonly associated with valuable minerals such as sphalerite, chalcopyrite, galena, gold as well as coal (Wang and Forssberg, 1991, Wang, 1995, Dimitrijevic et al., 1996, Jiang et al., 1998).Pyrite has very low economic significance and is usually removed from the valuable components by

The flotation separation and recovery approach is quite similar to the Pb-Zn sulphide separation process. Sphalerite is depressed with zinc sulphate addition to the grind with sodium sulphide as an option for enhancing pyrite depression. Copper is floated in the first differential flotation stage at a 10-11 pH with lime.
