CHAPTER 7 FLOTATION OF SULPHIDE MINERALS

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.

Collectorless flotation of Chalcocite by controlling redox ...

Using microflotation method, this study explored the collectorless flotation of Chalcocite and its dependence on the redox potential of pulp . Electrochemical studies were performed by cyclic voltammetry in specific potential ranges and at different pH values. The results show that significant floatability of Chalcocite occurs in the specific reducing conditions.

CONCLUSIONS The flotation of chalcocite and covellite is only strongly potential-depen- dent between - 300 and 400 mV vs. SCE. The onset of this potential region coincides well with the direct reaction between these sulphide minerals and xanthate ions producing CuEtX. Chalcocite flotation starts at - 300 mV and covellite flotation at mV vs ...

The flotation behaviors of chalcocite and molybdenite as a function of TGA dosage are indicated in Fig. 5. Recovery of chalcocite shows a substantially descending tendency with addition of TGA, while recovery of molybdenite is essentially constant with trivial decline. All this shows TGA is an effective inhibitor for chalcocite.
