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...
Data on the effects of different oxidative modification methods on the composition and flotation properties of spent mineral motor oils are reported. It was found that the preliminary ozonization of waste oils, in contrast to their thermal oxidation and treatment with hydrogen peroxide, increased the efficiency of the flotation of coking coal. The flotation properties of ozonized waste oils are improved...
