Abstract
The flotation of the semidull lithotype of coking coal by means of various reagents is studied. In the separation of the organic and mineral components of fusinized coal, heteropolar reagents with ether groups prove most effective. In flotation by heteropolar OPSB and TPREG reagents alone or in the presence of apolar reagents, the concentrate yield is increased by 23–24%, with significantly lower reagent consumption than when using hydrocarbon compounds based on kerosene.
