Abstract

Iron(III) sulfate or its mixture with aluminium sulfate can be used as a solid phase sulfatizing agent to destroy sodium aluminium silicates in red mud within 2 h at 200-500°C. These solid phase sulfatizing agents transform sodium aluminium silicates and basic sodium-compounds into water-soluble sodium sulfate without SO2 or SO3 evolution. By means of an aqueous leaching of the sulfatized red mud a raw material with high iron and low sodium content is obtained for blast furnace technologies.
