Abstract
During the combustion and enrichment of coals, slag and sludge wastes are formed, which are a source of environmental pollution. At the same time, these technogenic formations can be considered as a source of valuable components lying on the surface, used in high-tech industries and having high added value. To assess the content of rare elements, the analysis of ash and slag and sludge waste of some heat power plants and processing plants of the Kemerovo region-Kuzbass was carried out. This work is devoted to the results of studying the sludge of one of the enterprises of Kuzbass - the central processing plant "Berezovskaya". Researches have shown the possibility and prospects of complex waste processing with the sequential extraction of a number of components, including rare and rare earth elements.
Keywords
