The elementary steps in flotation are three: bubble-particle collision with the formation of a thin film of liquid between the bubble and particle; thinning of the film to the point of rupture; and rupture and recedence of the film, giving rise to a stable contact between the bubble and the particle. In flotation practice, mineral selectivity ...

Froth Flotation Process

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.
