Then air is passed through this mixture this results in the agitation of water in tank which cause the sulphide ore particles to stick with the oil and rise to the surface in the form of froth the gangue particles being heavier remain behind at the bottom of water tank the froth is separated and concentrated sulphide ore is obtained from it

Mineral processing played only a small role in the elemental sulfur industry when a sulfur ore was selected a typical method was grinding the sulfur ore to about 28 mesh followed by froth flotation flotation concentrates were melted and filtered to produce sulfur products with a grade of 995 these plants basically operated before 1960s 2
