froth flotation process for the concentration of sulphide ores

Froth floatation process: 1) Froth floatation process is based on the principle of difference in the wetting properties. of the ore and gangue particles with water and oil. 2)It is used for the extraction of those metals in which the ore particles are preferentially. wetted by oil and gangue by water
