Abstract
A huge number of coal enrichment dumps are stored on the territory of the Kuzbass coal basin. Coal waste accommodates a large quantity of rare and valuable chemical elements. The Krasnobrodskaya-Koksovaya coal preparation plant waste contains potentially valuable components. The forms of occurrence of such elements as Fe, Al, Cu, Zn, Ba, W, Ti, Zr, La, Y and Ag were revealed using by the mineralogical analysis. The mineralogical analysis showed that the proportion of the mineral component in the coal enrichment waste is 40.2% of which 29.52% are clay minerals. The clay minerals are sources of Al. The pyrite, chalcopyrite, galena, sphalerite, magnetite and others are sources of base metals. Xenotime and monazite found in the sample material are minerals-concentrators of rare earth elements. In addition, silver was found in the native form. The presence of these minerals in the coal wastes makes it a complex raw material and therefore a base metal, strategically important and rare elements could be extracted.
