A continuous, autogenous process for conversion of nonferrous metal sulfide concentrates to remove metal therefrom wherein oxygen-containing gas is fed to a molten concentrate charge, through fluid shielded nozzles of a substantially horizontal converter, wherein sulfur trioxide is fed along with the oxygen-containing gas, with the sulfur trioxide converted to sulfur dioxide within the converter to absorb heat from the charge and assist in control of the temperature thereof.
