ABSTRACT:
A separation process is disclosed herein for selectively removing agglomerated carbonaceous particles from aqueous suspension, the remaining inorganic particles being removed as a waste product. A source product containing finely divided carbonaceous particles and associated inorganic particles is treated by known techniques to cause the carbonaceous particles to agglomerate. The resultant mixture of such processes contains water, a liquid hydrocarbon, inorganic particles and the agglomerated carbonaceous particles. This resultant mixture is fed continuously into the vertical center of a mixing tank. The mixture is there agitated by an impeller which rotates in the horizontal plane. The agglomerated carbonaceous particles rise to the top of the mixture and are recovered as an overflow stream, the particles thereafter being rinsed with water and dried to produce the desired product. The heavier inorganic particles settle to the funnel-shaped bottom of the tank, and enter the inlet of an auger. The auger carries the suspended inorganic particles to an outlet which is located above the top of the mixture in the tank. The inorganic particles are thereby removed with a minimum amount of water, and they are disposed of in an appropriate manner.
