Abstract

In the presented article the authors talk about the difficulty of enriching coal sludge with a particle size of less than 0,5 mm. Effective enrichment methods involve the use of reagents. This has unfavorable effects on the environment. In their work, the authors show the possibilities of using a concentration table and confirm its effectiveness.

Keywords

Coal sludge, enrichment, commercial product, screw separation, coal slurry processing, concentration table.
