Flotation Process | Encyclopedia.com

May 08, 2018· 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 | Infoplease

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

Frothers & Froth Flotation | ArrMaz

During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.

Dissolved air flotation - Wikipedia

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter ...
