Title: Melt reduction of iron ore

Abstract: A method for reducing finely divided iron ore supplied to a ferrous melt, comprises inductively heating part of the melt at a heating rate higher than any heating of the balance of the melt so as to form in the melt an electrically heated part of the melt putting heat into the balance of the melt. The ore is injected substantially directly into this electrically heated part of the melt while the melt is supplied with carbonaceous material. The heating rate is maintained to keep the electrically heated part of the melt at a temperature sustaining the endothermic reaction between the iron ore and the carbonaceous material as required to reduce the ore to iron which then becomes a part of the melt.
