As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.
However, the sulphidisation of oxidised Cu–Co minerals and their flotation with xanthates remains a delicate and costly operation. It requires an optimal concentration of sulphide and sulphydrate ions in the pulp for the better flotation of useful minerals (Barbaro et al., 1997; Gush, 2005). In addition, the acquisition of sulphidisation ...
