Flotation Process | Encyclopedia

 · flotation separation A concentration process where by finely ground ore is dispersed in water containing a flotation reagent which causes selected minerals to become hydrophobic. Aeration and agitation of the suspension allows hydrophobic particles to float while unaffected minerals sink. The floating particles are skimmed off or overflow the flotation cell.

Write a short note on froth floatation process.

Froth floatation process is used for concentration of sulphide ores mainly. The particles based on differences in the ability air bubbles that selectively attach to specific mineral surfaces in mineral water slurry are separated by this method. In this method, crushed ore is suspended in water and air is passed through suspension.

Flotation techniques (most frequently used: zinc sulfate or Sheather''s sugar) use solutions which have higher specific gravity than the organisms to be floated so that the organisms rise to the top and the debris sinks to the bottom. The main advantage of this technique is to produce a cleaner material than the sedimentation technique.
