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.
Froth floatation process This process is based on the fact that the sulphide ore particles are only moistened with oil, whereas oxide and gangue particles are moistened by water. For this, the powdered ore is mixed with water and a little pine oil and whole mixture is then stirred vigorously through rotating paddle by blowing compressed air. The oil forms a foam or froth with air. The ore ...
Important Topics Chemistry Froth Floatation Process. In some cases for example, sulphides ores of copper, zinc and lead concentration is brought by this method.

In froth floatation process in the concentration of sulphide ore froth adsorbs ore particles. Solution Froth flotation is the process of selectively separating hydrophobic materials from hydrophillic. In case of sulphide ores, the ore particles are adsorbed on froth that floats and the gangue particles settle down in tank. Hence true,1.
