Recovery of high-grade copper matte by selective sulfurization of CuO–Fe2O3–SiO2–CaO system
The separation of Cu from the CuxO-FexO containing waste (such as copper slag and electroplating sludge) is always intractable by using pyrometallurgy method. The carbothermic reduction methods, as well as the conventional sulfurization technology by using sulfurization agent FeS2, will introduce lo...
