ABSTRACT:
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. The process is particularly useful for producing "super" clean coal.
