An experimental technique to prepare slags free from suspended matte was developed and applied to measure the solubility of copper in Fe- and SiO2-saturated fayalite slag at 1200°C. The copper solubility was found to be considerably greater than that attributed to oxidic loss assessed from the work of Ruddleet al and also greater than that in previously-studied slags containing sulfur together with lime or alumina. The solubility was related to the presence of sulfur in the slag, and the… Expand

FeO-Fe2O3-SiO2 slags were equilibrated in pure nickel crucibles under a CO-CO2 atmosphere. The Fe/SiO2 ratios in the slag were fixed at 1.51 and 1.97 at temperatures of 1200 and 1300°C. The CO2/COExpand
A Study on the Equilibrium between Copper Matte and Slag
Abstract Experiments on the equilibrium between copper matte and fayalite type slag were carried out under the condition of metallic copper (or γ-iron) and silica double saturation at 1473 K. It hasExpand
Equilibrations of copper matte and fayalite slag under controlled partial pressures of SO2
Equilibrium distributions of Cu, S and O between silica saturated fayalite slags and copper mattes (25 to 79 pct Cu) have been examined experimentally under controlled partial pressures of SO2. TheExpand
