On the Possibility of Waste-Free Use of Mineral Resources of the Angrensky Brain Coal Deposit

Abstract

The Angren lignite basin is a complex coal-kaolin deposit. Here, in addition to brown coal, there are large reserves of kaolin clays of two types - primary and secondary, occurring respectively in the soil and the roof of the coal strata. Secondary clays, in turn, subdivided into gray and variegated, which during overburden and mining of coal seams in the bulk go to the dump. Gray kaolins currently partially processed at the “Angren Kaolin” LLC factory in order to obtain enriched kaolin used for the production of building ceramics, etc.
