Iron ores consist of oxygen and iron atoms bonded together into molecules To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen Oxygen-iron bonds are strong and to remove the iron from the oxygen a stronger elemental bond must be presented to attach to the oxygen

This process consists of wood chips impregnated with varying amounts of hydrate iron oxide (Fe 2 O 3) This reacts with the H 2 S to form Fe 2 S 3 which may be regenerated with air Continuous regeneration is possible by injecting a small stream of air into the feed-gas stream which converts the sulfide to the oxide and liberates the elemental sulfur
