Summary:Procedure for enrichment of humic acids in coal characterised in that it comprises a natural mix, performed mechanically, of coal in solid form and an alkaline hydroxide in the form of MOH.The invention presented affords the main advantage of enabling coals with an average-low humic acid content to be converted into coals with average and average-high humic acid contents, by means of a simple process, easily scalable and replicable at industrial level, in an economic way that avoids having to manage aqueous suspensions.
