Surface tension during wetting of coal grains which flotate in one cell of IZ-12 floater after another as well as contribution of hydrophilic grains in each product were studied. The method of fractional surface flotation (FFP) was used to determine the surface tension during wetting of coal grains. It was found that use of fractional surface flotation and analysis of distribution of surface tension during wetting of coal grains in concentrates along the IZ-12 flotation machines enables an assessment of used technology and technological efficiency of the flotation concentrator.
