COAL BENEFICIATION IIM

Gravity Separation. To effect the gravity separation of coal and mineral matter, 500 g crushed coal (6 mm 0) were added to 2000 ml tetrachloroethylene (specific gravity 1.613) in a large beaker placed in a well ventilated hood. The mixture was stirred by hand to insure wetting of all particles, an d then it was allow ed to stand for 30 min.
