Froth flotation chemeurope

Froth flotation is a selective process for separating minerals from gangue by using 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.

Studies of Surfactant Behaviour and Model Surfaces

The function of the surfactants in the deinking process is both to promote ink detachment from the cellulose fibres in the repulping step but also to make the ink particles hydrophobic, aiding ink attachment to the air bubbles in the flotation cell. Anionic and nonionic surfactants are used to promote these processes, where fatty acids
