Principle- The basic principle behind the Froth Flotation process is the difference in the wetting ability of the ore and the suspended impurities. The particles are categorized into two types based on their wetting ability: 1. Hydrophobic 2. Hydrophilic If the suspended minerals are hydrophobic, they get attached to the froth and not to water.

Abstract Removal of gangue materials, principally silica and alumina, from a magnetically-separated, iron-rich fraction of bituminous coal fly ash shows promise of yielding an iron ore grade concentrate. As separated, the iron-rich fraction contains 65 to 75 wt. % iron oxides or about 50 % of the iron originally in the ash.

Pellets are obtained byadding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8]. This cohesive tension of fine particles due to water is called neutral tension.
