The article deals with the results of the material composition studying of the Kuzbasskaya coal preparation plant waste. Such toxic elements as arsenic, chromium, mercury, selenium, beryllium and vanadium are included into the composition of this material. The valuable impurity elements are silver, lanthanum, molybdenum, scandium, selenium, lead and yttrium. The ash content of the original fuel was 22.4 %, which indicated the presence of non-combustible phases represented by inorganic matter. The optical and mineralogical analysis determined that this waste was composed of coal (82.51 %), in addition, it contained carbonates, feldspars, quartz, clay minerals, as well as magnetite and iron hydroxides. Sulfides, monazite, rutile, zircon and micas were visualized in single grains.
