Flotation Cell an overview ScienceDirect Topics

Agitated flotation cells are widely used in the mineral processing industry for separating, recovering, and concentrating valuable particulate material from undesired gangue. Their performance is lowered, however, when part of the particulate system consists of fines, with particle diameters typically in the range from 30 to 100 μm.

Feb 04, 2021 flotation separation A concentration process where by finely ground ore is dispersed in water containing a flotation reagent which causes selected minerals to become hydrophobic. Aeration and agitation of the suspension allows hydrophobic particles to float while unaffected minerals sink. The floating particles are skimmed off or overflow the flotation cell.

Froth_flotation

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.
