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.

Sep 01, 2014  Effect of leaching with sulfuric acid followed by flotation on ash and sulfur removal. For optimal conditions, 43% of the ash and 52.9% of the pyrite sulfur (36.45% of total sulfur) were removed from bitumen. The leaching process was applied to the float samples using sulfuric acid. This process improved the ash and sulfur removal percentages.
