Abstract
Energy consumption may be minimized when reducing iron oxide with reducing gases which are at least partially re-circulated in the process and where the re-circulation gas is washed to remove the reaction product CO.sub.2 in what is known as a CO.sub.2 wash to enable it to be re-used, by the heat requirement necessary for regenerating the washing liquid in the CO.sub.2 wash being entirely or partially covered by the physical heat content in top gas from the shaft furnace and/or gas leaving the sponge-iron cooler of the shaft furnace.
