A method is disclosed for the production of form coke, such as coke for use in the smelting industry as blast furnace coke and also in electro-metallurgical facilities. The process consists of : coking a high volatile coal containing at least 35% volatile constituents so as to remove the volatile constituents to form a non-baking base coal; mixing a plurality of fine grain coal components together, of which at least one of the components comprises said non-baking base coal and at least one other component comprises a baking bituminous coal so as to form a mixture of such coals; subjecting the mixture to a degassing operation using highly volatile coals; coking the degassed mixture; and pressing the coke into briquettes.
