Abstract—Flotation wastes at OAO TsOF Belovskaya are studied with a view to their disposal in systems for the combustion of high-ash coal. Analysis indicates that, if the flotation wastes are mixed with regular coal, they may be used as fuel in low-temperature fluidized-bed furnaces. The introduction of such furnaces in the drying department at OAO TsOF Belovskaya is recommended, for use in the drying of coal concentrates.

Keywords: coal, flotation wastes, low-temperature fluidized-bed furnace
