Popis: In the classical pyrometallurgical route for copper production from sulphide concentrates, the treatment of slags aims to recover copper through the coalescence of copper metal and copper sulphide particles. To assist with this settling process, a reductant is added to the slag to reduce the spinel precipitated phases (magnetite) in order to diminish the viscosity of the slag. While the impact on viscosity is typically the majority of reports in the literature, there is also the potential to reduce Cu2O and Cu2S dissolved in the slag. This can result in improved settling and increased recovery of copper.
