the flotation of iron ore, phosphate and coal. Flotation columns differ dramatically from mechanical flotation machines in . several ways: • there is no mechanical agitation/shear • the cell is relatively tall and narrow • gas bubbles are generated by sparging • froths typically are deeper, and wash water typically is liberally applied

Froth flotation is a process for selectively separating of 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. It has been described as the single most important operation used for the recovery and upgrading of sulfide ores . The development of froth flotation
