<p>Iron ore is reduced by reaction with reducing gas in a furnace 2. The iron is melted and a solid carbonaceous material is gasified both in a melter-gasifier 4. The gasification of the carbonaceous material yields a reducing gas for use in the furnace 2. At least 25% by weight and preferably all of the carbonaceous material comprises coal char formed by the partial oxidation of coal in a separate reactor 6. <IMAGE></p> |
