Extraction of iron from copper-plant slag |

2017-01-05· 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

Recovery of Valuable Metals from Copper Slag

A novel hydrometallurgical method was developed to recycle valuable metals of Si, Fe and Cu from copper slag. The leaching rates of 98%, 99% and 91% for SiO2, Fe and Cu, respectively, were obtained under optimized parameters: solid-to-liquid ratio is 1:10; concentration of hydrochloric acid is 35%; the reaction time is 2 hours and at 80-90°C.
