A process is disclosed for the beneficiation of coal by selective caking, in which process a caking mixture is employed consisting of: - one or more solvents selected from among light hydrocarbons having boiling points not higher than 70 DEG C; - a non-ionic, oil-soluble additive obtained from controlled propoxylation of the phenolic fractions derived from coke-oven tars; - and possibly one or more heavy co-caking agents selected from among coal-derived oils having boiling points between 200 and 400 DEG C, or the residual products of petroleum refining or mixtures of the same. |
