FIELD: process engineering.
SUBSTANCE: invention relates to concentration of minerals and can be used for concentration of coal, slurry coal, industrial carbon, etc. Proposed method comprises oil sintering of coal particles at mixing of suspension by rotary mixer for 2-3 min. Intensive mixing of slurry coal or coal and water is carried out at 1000-1500 rpm of mixer.Then, oil reagent-collector is added in amount of 8-10 wt % of coal to mix the obtained mix at 1000-1500 rpm for 5-8 min with gradual increase of mixer rpm to 4000 with at interval of 1-2 min.
EFFECT: higher efficiency of concentration.
