General Characteristics of the Refuse Heaps of Eastern Donbass and Products of their Processing as Raw Materials for the Production of Wall Ceramics

The relevance for the south of Russia of the search and creation of a new non-traditional raw material base of wall ceramics in connection with the decreasing availability of traditional raw materials – loams is shown. The classification according to the volumes of composing rocks is presented: mine waste heaps and dumps of processing plants of Eastern Donbass. Their characteristics of mineral and chemical composition are given. It is noted that coal-industrial waste is very diverse in its mineral composition, which was a serious deterrent to their industrial development. The classification of waste materials processing products by lithological composition, coal content and fractional composition of composing rocks is presented. According to the fractional composition, 5 groups were allocated, four groups were allocated according to the mineralogical and petrographic composition, 4 groups were also allocated according to the coal content. It is noted that small and thin materials contain coal in an increased amount and due to this cannot be considered as the main raw material for the production of ceramic stones. Materials of the middle group by grain composition (2–5 mm, screenings) can contain up to 2–3% coal in their composition and are most often represented by a mixture of mudstones, siltstones and sandstones with a predominance of one or another variety of rocks. Due to these features, the materials of the middle group are of the greatest interest as the main raw materials for the production of large-format high-void ceramic stones and bricks.
