OverviewHistoryIndustriesPrinciple of operationScience of flotationFlotation equipmentMechanics of flotationChemicals of flotation

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. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copper- and le

Froth Flotation Circuit Design And Basic Testwork ...

Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed ...

Dissolved Air Flotation - an overview ScienceDirect Topics

Dissolved air flotation operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the ‘float’, is skimmed off as sludge (Section 7.19).The clarified water is removed from the bottom and is sometimes called the subnatant or ‘floated’ water.
