Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing, paper recycling and waste water treatment industries Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century

Froth Flotation Charles Kubach, 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
