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 1200176C 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 ...Online Consulting
