US4270926A Process for removal of sulfur and ash from

A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates. The coal-oil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step.

Reduction of Sulfur and Ash from Tabas Coal by Froth Flotation

siderite, etc., sulfate and sulfides, etc., are the major ash-forming minerals in coal [1]. However, high sulfur coals can be upgraded by desulphurization through physical, chemical and bio-technological processes. Oneof the most suitable physico-chemical methods is froth flotation for removal of pyritic sulfur from coal [2].

US4272250A Process for removal of sulfur and ash from

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.
