Abstract

An aqueous slurry of coal is disclosed, together with the related processes for producing it, said aqueous coal slurry having a concentration comprised within the range of from 60 to 80% by weight and containing a polyelectrolyte selected from the monovalent cation salts of polymerized naphthalenesulphonic acids, the characteristic of such a slurry consisting in that on the surface of coal, constituted by particles with a granulometry not greater than 300 mu m, a heavy liquid is present, which is obtained by means of the distillation of pit coal tar, or a fuel oil deriving from mineral oil, in an amount comprised within the range of from 0.1 to 2% by weight relatively to same coal.
