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 DEG 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 DEG to 400 DEG C. or the residual products from oil processing or blends thereof.
