flotation cell level controller froth flotation float buoyancy is sensitive partially to density of the froth layer, and to a lesser degree the pulp density. a disadvantage of the float buoyancy method is the possibility for accumulation of congealed froth on the float upper surface, adding weight to decrease float buoyancy. the float can be flushed with a water stream to overcome this difficulty.

froth flotation overviewfroth 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

antimony trioxide typical steps include mining, crushing and grinding of ore, sometimes followed by froth flotation and separation of the metal using pyrometallurgical processes (smelting or roasting) or in a few cases (e.g. when the ore is rich in precious metals) by hydrometallurgical processes. these steps do not take place in the eu but closer to the mining
