Abstract
The annual growth in the volumes of dumps and landfills of the coal industry leads to the formation of a number of problems of negative anthropogenic impact on the environment and human life and health. The search for a solution to this problem attracts the attention of many researchers who consider these wastes as man-made mineral raw materials containing macro-components (compounds of silicon, aluminum, iron, calcium, etc.) and micro-components (dispersed, noble metals, rare and rare-earth elements). At present, the most researched direction is the use of coal industry waste as raw materials for building materials, while technologies for complex processing in order to extract rare and rare earth metals are undergoing the stage of searching for the most optimal and economically profitable options. In each of the described directions, an important requirement for raw materials is the content of the carbon component, since the presence of carbon significantly reduces the strength of building materials and increases the volume of reagents in chemical methods of complex processing.
This paper presents data obtained as a result of experiments on the extraction of coal concentrate from coal enrichment waste from the central processing plant "Berezovskaya" of the Kemerovo region-Kuzbass. The possibility of further enrichment of waste by coal to produce a product suitable for combustion in power plants is shown. The remaining mineral part is suitable for the subsequent extraction of rare and rare earth elements.
