Extraction of iron from copper-plant slag SpringerLink

 · In the production of copper from sulfide ore slag accumulates at the processing plant. In the present work the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag may be converted to metallic form by the gasification products of carbon in

Iron ExtractionW3spoint

Iron Extraction. The common ores of iron are its oxide hematite Fe 2 O 3 and magnetite Fe 3 O 4. They can be reduced to iron by heating them with carbon in the form of coke. The coke burns in an exothermic reaction. At the high temperatures the carbon dioxide reacts with more coke to make carbon monoxide.
