Lead smelter slags from two different sources have been leached using sulfurous acid/oxygen as the leachant so as to dissolve zinc and copper values but not the contained iron. The differences in the leaching behaviour are explained in terms of the different slag compositions. The mixed control shrinking core model adequately described the relationship between fractional extraction and time.
