froth flotation wastewater treatment

About this site

Mar 01, 2002  In mineral flotation it is necessary to produce a stable froth at the free surface of the flotation cell. In applications to wastewater treatment an stable foam is not required. In mineral flotation, the overall process is economically attractive. In environmental application, usually flotation means an extra cost.

About this site

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 makes processing complex (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
