1-1-2020· The surface hydrophobicity and floatability of the copper sulphides upon oxidation in typical alkaline flotation conditions are primarily controlled by two opposite processes, dissolution of metal ions that produces sulphur-rich hydrophobic surfaces, and precipitation of metal hydroxide and oxide that produces hydrophilic surfaces (Fairthorne et al., 1997).

US3596838A - Flotation of sulphide ores - Google Patents

Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step. The first step comprises conditioning a pulp of the ore in the presence of at least one alkaline agent selected from a group of agents which is defined in the specification which follows.
