Abstract: A process is disclosed for beneficiation of coal by selective caking, in which process a caking mixture is employed consisting of:one or more solvents selected among light hydrocarbons having boiling points not higher than 70.degree. C.;one or more non-ionic additives selected among oil soluble propoxylated or propoxylated-ethoxylated phenolic or alkylphenolic compounds;possible one or more heavy co-caking agents selected among coal-derived oils having boiling points between 200.degree. C. and 400.degree. C., or the residual products of petroleum refining, or mixtures thereof.

Abstract: 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.degree. C.;a non-ionic, oil-soluble additive obtained from controlled propoxylation of the phenolic fractions derived from cake-oven tars;and possibly one or more heavy co-caking agents selected from among coal-derived oils having boiling points between 200.degree. and 400.degree. C., or the residual products of petroleum refining or mixtures of the same.

Abstract: A process is disclosed for the beneficiation of coal by means of selective agglomeration, wherein an agglomerating blend is used, which is constituted by:one or more main agglomerating agent(s), selected from the light hydrocarbons having a boiling temperature not higher than 70.degree. C.,one or more non-ionic additive(s), selected from oil-soluble ethoxylated compounds;one or more heavy co-agglomerating agent(s) selected from oils deriving from the distillation of coal-tar, having a boiling temperature comprised within the range of from 200.degree. to 400.degree. C. or the residual products from oil processing or blends thereof.
