Abstract
The removal of copper dissolved in liquid stags by pyrometalIurgical means such as gaseous reduction and sulfidization is thermodynamically investigated. The lowest level possible for copper content is theoretically determined and compared. The results show that gaseous reduction is not as effective as sulfidization. Slags with very low levels of dissolved copper can be obtained with sulfide treatment. Effects of temperature, slag and matte composition have also been investigated.
