Abstract: A process for producing iron metal and slag by smelting iron-containing source material, having iron present as oxide and/or a partially metalized state, in a reactor containing a molten bath comprising or having a slag phase, utilises injection of fuel/reductant and oxygen-containing gas into the slag, by at least one top-submerged lance, to generate heating and reducing conditions in at least one reducing region in the bath. The source material is fed to the reactor, together with additional reductant and with flux, at or adjacent to the at least one reducing region, to subject the source material to smelting reduction which generates combustion gases comprising CO and H2. The rates of injection of the oxygen-containing gas and fuel/reductant by said at least one lance are controlled to achieve required, sufficient reducing conditions; and, in the reactor above the bath, the combustion gases generated by the smelting are post-combusted.
