    • Abstract
  • In order to explore the physical properties of magnetite in the roasted copper slag in the molten state, a melt oxidation roasting experiment was conducted on the copper slag in a CO/CO2 atmosphere. The effects were investigated of CaO addition and calcination temperature on the transition process of Fe2SiO4 to Fe3O4 in the slag, and the migration and enrichment of Fe3O4. The addition of CaO promotes the conversion of Fe2SiO4 to Fe3O4 in the slag and the migration and enrichment of Fe3O4, and the properly selected roasting temperature can maximize the migration and enrichment of Fe3O4. Finally, it was found that the addition of CaO was 25 % of the mass of the copper slag, the calcination temperature was 1 300 ℃, the holding time was 2 h, and the volume of CO2 and CO was 190:10. The Fe2SiO4 in the copper slag had basically completed the conversion to Fe3O4 and its migration and enrichment degree was better.
