Separating and Recycling of Fe, Cu, Zn from Dumped Copper Slag by Microwave IrradiationAssisted Carbothermic Method
Iron, copper and zinc were separated and recycled from dumped copper slag using a carbothermic method in the presence of microwave irradiation. Iron in the form of fayalite and magnetite in the slag was reduced to metal iron while zinc was evaporated and captured as zinc oxide powder. Results indicated that metallization rate of iron could reach 91.38~93.45 wt% and zinc recovery efficiency was 90.5 wt% when the new methodology was employed, and that reaction temperature was 100°C lower compared to that of traditional processes, reaction time of the new process was decreased by 90 min.
期刊介绍:
The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
