Application of flotation for the separation of metal ...

The flotation process was originated from the mineral processing field, before applied to water/wastewater engineering, mainly as a solid/liquid separation technique; it offers several advantages over the more conventional methods (e.g. sedimentation), such as faster separation kinetics, higher flexibility and production of more concentrated sludge, occupying smaller volume (Matis, 1995).

Froth flotation - Wikipedia

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.

Separation process - Wikipedia

Complete and incomplete separation. In some cases, separations require total purification, as in the electrolysis refining of bauxite ore for aluminum metal, but a good example of an incomplete separation technique is oil refining. Crude oil occurs naturally as a mixture of various hydrocarbons and impurities. The refining process splits this mixture into other, more valuable mixtures such as ...
