Quality of coals is deteriorated. This leads to necessity to improve technologies for their cleaning. In connection with this, technology for flotation of coals has been enhanced. Chemical compositions of the coals have been taken into account in this case. Measures for environmental protection have been taken. Investigations of process of coal flotation have been performed. Results of the investigations have shown that utilization of surface-active agents such as peat humates makes it possible to improve efficiency of the process. The peat has been heat-treated. Humates of heat-treated peat have been efficiently utilized in the process.
