How Froth Flotation Works - Mine Engineer.Com

The process of froth flotation is generally described as a physical-chemical action, where a mineral particle is attracted to, and attaches itself to the surface of a bubble, and is transported to the surface of a cell, where it overflows into a discharge launder, usually with the assistance of paddles, rotating in the direction of the launder (which is typically …

froth layer. Particles that are retained in the froth are recovered at the lip of the froth weir at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles.
