Abstract

The article discusses the issue of processing coal sludge from Kuzbass, which negatively affects the ecosystem of the region. Known modern methods of their processing do not always meet environmental requirements, so the demand for environmentally friendly technologies remains in the first place. The author presents the results of laboratory and industrial tests performed using gravitational enrichment technology based on the screw separation method, which, as everyone knows, is distinguished by its environmental friendliness and simplicity.

Keywords

Coal sludge, Enrichment, Commercial product, Spiral separation, Coal sludge processing, Environmentally friendly technology.
