Abstract: A process for direct smelting a metalliferous feed material containing at least 0.2 wt.% sulphur in a smelt cyclone and a direct smelting vessel containing a bath of molten metal is disclosed. The process is characterised by maintaining an oxygen potential in the smelt cyclone that is sufficient so that an offgas from the smelt cyclone has a post combustion degree of at least 75%.

Abstract: A smelting apparatus that includes (a) a smelting vessel. (4) that is adapted to contain a bath of molten metal and slag and (b) a smelt cyclone (2) for pre-treating a metalliferous feed material positioned above and communicating directly with the smelting vessel The apparatus also includes an oft-gas duct (9) extending from the smelt, cyclone for discharging an off-gas from the smelt cyclone. The off-gas duct has an inlet section (18) that extends upwardly from the smelt cyclone and is formed to cause off-gas to undergo a substantial change of direction as it flows through the inlet section of the off-gas duct.
