Abstract: Chemical reactions of sulphur compounds in the electrolyte used for electrowinning of aluminium were investigated. It was found that sulphate ions are reduced both by carbon and by aluminium under the formation of sulphides and SO₂ . The amount of sulphur reduced to sulphides was in some cases as high as the amount of sulphur escaping in the form of SO₂.
