Abstract

Experimental investigation of the gas/matte/spinel equilibria in the Cu–Fe–O–S system was undertaken at 1250°C, P(SO2) = 0.25 atm, and a range of oxygen partial pressures. The experimental methodology involved high temperature equilibration using spinel substrates in controlled gas atmospheres (CO/CO2/SO2/Ar), rapid quenching of the equilibrated phases, followed by direct measurement of phase compositions using electron probe X-ray microanalysis technique. The influence of temperature on the gas/matte/spinel equilibria and comparison with previous studies are provided. The new data obtained in the present study can be used for revision of the existing thermodynamic database for the copper-containing systems.
