Beneficiation of Fine Coal: Froth Flotation Efficiency

Grootegeluk. The ultra-fine coal, which cannot be beneficiated by spirals, became the new feed to froth flotation plants. From about 1985, starting at the now-closed Landau III plant1, a number of experiments were conducted to evaluate the potential of froth flotation for the beneficiation of Witbank-type ultra-fine coal.

Flotation Froth an overview ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). likewise the new coal washeries should also have provision for fine coal treatment. The beneficiation of fine coal is a more complex and costly operation as compared to that

Beneficiation Wikipedia

First froth flotation is used. Due to similarities in mineralogy there is not complete separation after flotation. The gangue that is found with lithium after the flotation are often iron bearing. The float concentrate goes through magnetic separation to remove the magnetic gangue from the nonmagnetic lithium. See also. Coal preparation plant
