The laboratory scale results of a process for direct smelting of copper sulfide-copper oxide ores under inert atmosphere are discussed in terms of reaction kinetics. The theoretical and experimental analysis of the process revealed that copper metal can be produced from sulfide and oxide ore concentrates continuously via several competitive and consecutive second-order reactions.
The experimental reactant mixture was comprised of Cu2S-FeS-Cu2O-SiO2. The smelting process proceeds without injection of air into the system. The role of oxygen associated with cuprous oxide is similar to that of the oxygen in conventional copper converting.
