what is froth flotation

    Frothers, Froth flotation is a physicochemical process that separates particles based on differences in surface wettability Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles (Fig 17) A chemical reagent, called a frother, is ,Froth Flotation Circuit Design And Basic Testwork ,, Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potashWrite the principle behind the froth floatation process ,, Froth floatation process is based on the principle that the metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water Collectors attach themselves by polar groups to grains of minerals which then become water repellent and thus, pass on into the frothFROTHING AT THE LIP, the Froth Carry Rate (FCR), and is expressed as t/m2h - the amount of material that 1m2 of froth can carry to the launder lip in an hour In a flotation cell the froth surface area is determined by the amount of froth crowding Designing a flotation cell with a low froth surface area, (high degree of froth ,Flotation Frothers, Metallurgical ContentFrothers behaves as SoapFrothing ReagentsSURFACE TENSIONCreating a Froth for FlotationTesting Frother Performance The next reagent that is added is the Flotation FROTHER The frother strengthens the surface tension of the air that is injected into the flotation cell As the air rises in the shape of bubbles, they come into contact with the mineral laden collector which ,.
