Abstract
The invention relates to a process for the beneficiation of solid fuel, in which a heat treatment at elevated pressure is applied to an aqueous suspension of the solid fuel in a finely divided form in the presence of an additive which, under the prevailing conditions, causes water-insoluble sulphur compounds to be converted into soluble compounds, after which fuel and water are separated.
