  • Sulphide Flotation - an overview | ScienceDirect Topics

    Sulphide Flotation. In practice, sulfide flotation plants operate at pulp potentials that are in the range of +50 to +200mV versus SHE (Grano, 2004) and the value depends on the pulp pH, type and quantity of sulfide minerals, the type and quantity of grinding media (Rao et al., 1976), and the amount of air–pulp contact in and after the grinding circuit (Teague et al., 1999b).

    Synopsis. This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristics.
