Abstract

A smelting apparatus that includes (a) a smelting vessel () that is adapted to contain a bath of molten metal and slag and (b) a smelt cyclone () for pre-treating a metalliferous feed material positioned above and communicating directly with the smelting vessel The apparatus also includes an oft-gas duct () extending from the smelt, cyclone for discharging an off-gas from the smelt cyclone. The off-gas duct has an inlet section () 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.
