抄録

As a fundamental study on the behavior of arsenic in reduction smelting of nonferrous metals and treatment of byproducts and wastes, distribution equilibria between the speiss and slag phases were investigated. The iso-curves of copper and iron activities in the Cu-Fe-As system at 1,423 K, which were determined on the basis of the arsenic activity and the phase relations between the γ-Fe solid solution and liquid phases, presented some characteristic features on a ternary Cu-Fe-As diagram. The distribution ratios of arsenic and copper between the speiss and calcium-ferrite or iron-silicate slag phases, defined by L_As^s/c = (mass % X in slag) / (mass % X in speiss) with X = As or Cu, were determined at 1,473 K for the speiss whose compositions were on the iso-curves of iron activity. It was found that L_As^s/c decreased remarkably with increasing iron activity and the observed behavior could be explained reasonably based on the fundamental thermodynamic properties of the speiss and slag components.
