Mineral Flotation SpringerLink

In the extraction of metals from their ores, the process of mineral flotation plays a most important role. Flotation provides the means of separating and concentrating the valuable components of an ore to produce a grade of mineral concentrate suitable for feeding to efficient pyrometallurgical or hydro-metallurgical operations.

CHAPTER 7 FLOTATION OF SULPHIDE MINERALS

2015-10-19  Flotation of Chalcocite (Cu 2 S) Chalcocite (Cu 2 S) and chalcopyrite (CuFeS 2) are the two most commonly floated copper sulphide minerals. Bornite (Cu 5 FeS 4) and covellite (CuS) and energite (Cu 3 AsS 4) are normally present in lesser quantities. The complete flotation of chalcocite is achieved between ph = 1 to ph = 10 with ethyl xanthate.
