In froth floatation process sulphide ore is shaken with pine oil and water, the ore particles are adsorbed on froth that floats and the gangue particles settle down in tank. Thus, role of adsorption in froth floatation process can be understood as following processes. (i) Adsorption of pine oil on sulphide ore particles.

1. Concentration of pulp. In practical application, the concentration of pulp needs to be determined according to the nature of flotation ore and relevant technical requirements. When the ore is roughed, the pulp concentration is 25% ~ 35%, and the flotation fine particles and the ore with high mud content is 10% ~ 20%.

The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3 ), magnetite (Fe 3 O 4 ), siderite (FeCO 3 ), and iron pyrites (FeS 2 ) can be separated by the process of magnetic separation.
