Abstract
During the combustion and enrichment of coal, 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 raw materials lying on the surface, used in high-tech industries and having a high added value. In this paper, we consider the sludge of the enterprise "Berezovskaya". Determination of physical and chemical properties of ash content and solubility according to GOST 11022-95 "Method of slow ashing" and GOST 25818-2017 "Fly ash from thermal power plants for concrete". Studies have shown the possibility and prospects of complex waste processing with the successive extraction of several components, including rare elements and rare earth elements.
Keywords
Coal, Ash slags, Coal sludge, Elemental analysis, Rare and rare earth elements.
