Flotation Process | Encyclopedia

2018-5-8 · 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.

Flotation Process

In flotation process, the gas or air bubbles are introduced through culture suspension, and the microalgal biomass get attached to gaseous molecules and accumulated on the liquid surface. This method is particularly effective for thin microalgae suspension that could be simply gravity thickening.

Mineral Flotation | SpringerLink

The flotation process involves crushing the ore to liberate separate grains of the various valuable minerals and gangue components, pulping the ore particles with water, and then selectively rendering hydrophobic the surface of the mineral of interest. A stream of air bubbles is then passed through the pulp; the bubbles attach to and levitate ...

Flotation

Flotation is a technique, widely used by the mining industry, for the separation of minerals, phosphates, or coal from gangue. Coal and minerals particle size and surface hydrophobicity are two main parameters that affect three key steps in froth flotation process: particle–bubble collision, adhesion, and detachment.
