ABSTRACT OF THE DISCLOSURE Process and apparatus for the production of liquid crude iron and reduction gas in a smelting gasifier, in which particles of iron sponge, possibly with the addition of additive materials, are melted to form liquid crude iron or steel precursor material, and the heat required for the melting operation and reduction gas are produced from feed coal and oxygen-bearing gas which is injected above the melt. A fluidised bed of coal is formed in the smelting gasifier, the temperature in the lower region of the fluidised bed (high- temperature zone) being maintained at a value of from 2000 to 2500°C by the feed of the oxygen-bearing gas. This feed is in the lower region of the fluidised bed. The temperature of the fluidised bed decreases in an upward direction, to a value of from 1000 C to 1400°C, and the height of the fluidised bed is at least 1.5 metres, so that even larger particles of iron sponge which are more than 3 mm in size are markedly retarded by the dynamic pressure and uplift force in the fluidised bed and the temperature of such iron sponge particles is increased by a substantial amount by the heat exchange with the fluidised bed.
