Froth floatation process is used for the sulphide ores. In this method, wetting of the ore by an oil takes place. A strong current of air is blown through the suspension, producing a heavy froth or foam on the surface. The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to the surface by films of oil The froth is skimmed off, the gangue settles down on the bottom

(A) The concentration of ore involves physical and chemical methods. Froth floatation method is the physical method for the separating mineral from the gangue. (B) It is based on the difference in wettability of different minerals. The metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water

Aug 01, 2011 · High grade sulphide zinc ores. Currently, zinc is produced mainly from zinc sulphide ores because sulphides are easy to separate from gangue and to concentrate by conventional froth flotation processes (Li et al., 2010a). Zinc from zinc sulphide concentrates is usually produced using the roast–leach–electrowin (R–L–EW) process

Froth flotation, also called ore flotation when used in mining applications, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation

The process is best suitable for sulphide ores. The process is based on different wetting characteristics of the ore and gangue particles with water and pine oil. The ore is wetted by oil and impurities are wetted by water. Ore particles are adsorbed on potassium or sodium ethyl xanthate (as a collector) and come at the surface along with the froth
