ABSTRACT:
A process for reducing the sulfur and ash content of coal particles wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates having modified particle size and density characteristics. The coal-oil aggregates are separated from ash and mineral matter in the slurry by gravitational means. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step. Recovered coal particles comprise a substantial part of the feed carbon values.
