; ;
A process is disclosed for the production of beneficiated coal and coal slurries having low ash, and sulfur involving admixing coal in an aqueous medium with a surface treating admixture comprising a polymerizable monomer, polymerization catalyst and a liquid organic carrier thereby rendering said coal highly hydrophobic and oleophilic. The resultant beneficiated coal product is formed into coal slurries, such as coal-oil mixtures.
