OverviewIndustriesHistoryPrinciple of operationScience of flotationFlotation equipmentMechanics of flotationChemicals of flotation

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makesplex that is, mixed ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and

The Application of Xanthate in Froth Flotation Process

Xanthate Application in Sphalerite Froth Flotation. The sphalerite which surface is clean have low floatability. If the low grade xanthate is directly used for its flotation, the recovery rate is low, so it is necessary to use high grade xanthate to process the sphalerite. However, after activation of the copper salt activator, the surface of the sphalerite is easily adsorbed by copper ions

Flotation of Nickel Copper Sulphide Ore: Optimisation of

Abstract Froth flotation is widely used for concentration of base metal sulphide mineralsplex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a whole is always maintained. In this study, the
