Abstract

A method for producing a molten iron from a compact containing a carbonaceous reductant and an iron oxide is carried out extremely efficiently with a simple operation. The compact is supplied to a molten iron bath or a molten slag on the molten iron bath so as to float on the molten iron bath and/or the molten slag such that a part or most of the compact surface is substantially exposed to a high temperature gas atmosphere in the furnace for taking in a reduced iron generated by the reduction of the iron oxide in the compact.
