Abstract

The article presents the results of the enrichment of coal sludge from the branches of Krasnobrodsky coal mine, Kedrovsky coal mine and Bachatsky coal mine of Kuzbassrazrezugol JSC. The author presents the results of technological tests, during which it was possible to obtain coal concentrates suitable for use in the energy industry. Coal concentrates were obtained using a technology based on the use of screw separation.

Keywords

Coal sludge, enrichment, commercial product, spiral separation, coal sludge processing, Kuzbass.
