The invention consists of a process for manufacturing ashes from the combustion of coal, this process comprising at least one step of bringing the coal into contact with an absorbent agent on the one hand, this absorbent agent being, on the other hand, contained in an aqueous phase in the presence of a (meth)acrylic dispersant, preferably a (meth)acrylic comb polymer. Thus the emissions of carbon dioxide and likewise the compounds based on sulphur, nitrogen or mercury which result from the combustion of coal are effectively combated.
