Abstract

Vital differences of the chemical composition and basic technological properties and the flotation concentration of the petrographic lithotypes of laminated coal of the Balakhon series of Kuzbass are considered. It is shown that the efficiency of flotation of the lithotypes is determined by the special features of the distribution and combination of the organic and mineral components of coals. Low-ash semi-dull lithotype with a high yield of concentrate is floated with a traditional nonpolar reagent based on kerosene. The efficiency of flotation of high-ash bright lithotype increases with the use of flotation agents with heteropolar properties.
