摘要：

New data on gas/slag/matte/spinel equilibrium in the Cu-Fe-O-S-Si system at T=1200 degrees C and P(SO2)=0.25 atm covering a wide range of matte grades for copper smelting and converting are presented. High temperature equilibration and rapid quenching technique, followed by Electron Probe X-ray Microanalysis are used. The use of substrate made of solid spinel ensures equilibration strictly within the Cu-Fe-O-S-Si system and avoiding contaminants from crucible. The research is extended to measure partitioning of minor elements between slag and matte phases using this technique based on microanalysis. The system selected closely resembles the equilibrium condition of the actual copper smelting process. The information provided is essential for the evaluation of effect of fluxing towards the amount of chemically dissolved copper and quantity of solid in the slag. Present study is part of a larger integrated experimental and thermodynamic modelling research program on copper-making high-temperature systems.
