Studies on Separation of Macerals from Coal by Froth ...

Therefore, the flotation rate constant eventually becomes a function of maceral percentage of a coal particle. In the present paper, an attempt has been made by performing size-wise flotation tests using a sub-bituminous rank coal and flotation kinetics have been established based on maceral percentage reporting to concentrate at different time intervals of flotation.

US4244813A - Method of increasing fine coal filtration ...

Fine coals suspended in a coal flotation froth are more efficiently filtered when the flotation froth is subjected to a thickening operation prior to filtration. The thickening operation is accomplished by the use of a clarifier or thickener.

US4676804A - Coal cleaning by gaseous carbon dioxide ...

A process for froth flotation of coal using gaseous carbon dioxide includes a preconditioning treatment of the coal with gaseous carbon dioxide followed by froth flotation, preferably also using gaseous carbon dioxide. The pretreatment causes the coal to show improved results in that less reagent promoter and frother are required, and the flotation time is reduced.
