Recent advances in fine coal beneficiation SpringerLink

The quantum of coal fines below 6 mm in run-of-mine ROM coal has been increasing due to progressive mechanization of mining methods which has created a substantial incentive, worldwide, to develop suitable fine coal beneficiation techniques. The majority of the efforts have been directed toward reduction in ashsulfur contents in clean coal. The beneficiation techniques may be broadly ...

1 Froth Flotation Fundamental Principles

1.4 Collection in the Froth Layer Once a particle and bubble have come in contact, the bubble must be large enough for its buoyancy to lift the particle to the surface. This is obviously easier if the particles are low-density as is the case for coal than if they are high-density such as lead sulfide. The particle Froth
