Abstract: The results of tests of water sodium of sodium salts mixture of low monobasic C1 – C6, C8 and bi-basic C2 – C6 carbon acids which are byproducts of caproluctam production as activator of processes of coal gravity dressing in water heavy me-dium of ZnCl2. The extent of coal dressing with available activator 1,5-2,0% of coal mass in heavy medium increases by 27%. The duration of primary sludge flow clarification decreses by 8 times.

Key words: coal dressing heavy medium gravity activator concentrate sludge flow ash content sludge clarification kinetics
