Froth flotation

HistoryIndustriesPrinciple of operationScience of flotationFlotation equipmentFroth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater 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 quot;the single most important operation used for the recovery and upgrading of sulfide oresquot;. The development of froth flotation has improved the recovery of valu
