Abstract:In this paper, the feasibility of electrolysis of Cu 2 S and FeS in sulfur-containing carbon saturated iron melt aided by liquid lead cathode is studied by cyclic voltammetry and potentiostatic electrolysis at 1300 °C. The Cu 2 S and FeS are electro-reduced on the lead cathode and the product copper dissolve into the liquid lead while the product iron dissolves into iron melt due to the difference of solubility. An insert graphite rod in iron melt was used as the anode, on which the S 2− is oxidized to S. This… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
