The froth flotation test is conducted to design fine coal beneficiation circuit in CPP In India, fine coal beneficiation is generally performed through froth flotation technique which uses reagents for the separation of coal from impurities The standard flotation test gives good results as far as the quality of coal is within a range and thus same reagents are used in washery as in the The froth flotation of coal is conducted in the presence of a conditioner of an oxygen containing compound of the formula: Rsub1 ORsub2)subn (I) wherein R 1 and each R 2 are independently saturated hydrocarbyls and n is from 1 to about 3USA Method for the froth flotation of coal desulfurization) compared to using twostage froth flotation This is because coal flotation is based on hydrophobicity of coal, while gravity separation takes advantage of the large difference in densities between coal and pyrite Coal flotation Waterberg Witbank Frother dosage (MIBC) 011 kg/t 028 kg/t Collector type Nalflote 9858 Nalflote 9858 Collector dosage 14 kg/t 14 kg/t COMPARISON OF FROTH FLOTATION AND GRAVITY SEPARATION
