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 direct smelting plant for producing molten metal from a metalliferous feed material using a molten bath based direct smelting process is disclosed. The plant includes a plurality of gas injection lances to inject the oxygen-containing gas into the vessel that extend downwardly through openings in a side wall of a direct smelting vessel.
