A method is described of producing water-resistant carbonaceous agglomerates suitable for use as a fuel comprising: providing a solid, oxidized carbonaceous material including chemically combined oxygen as humic acid or humate salt; extracting humates from the oxidized material into aqueous alkali solution to form a binder solution; providing particulate carbonaceous fuel material having a heating value greater than that of the oxidized carbonaceous material; blending the binder solution in mixture with the particulate fuel to permeate the humate solute into the fuel particles; consolidating the particulate fuel into agglomerates of convenient size for fuel use; and drying the agglomerates to reduce moisture content and convert the humate solute into a solid, water-resistant binder material throughout the agglomerate.
