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%.
