Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.
White Pine reverberatory furnace slags contained economically recoverable amounts of copper for a variety of reasons. Among them: White Pine concentrates yield extremely high matte grades (65+% Cu) and viscous slags. The viscous slags hinder matte settling causing matte “prill” entrapment in the slag. White Pine’s total refined copper output is accomplished through fire refining ...

processed for copper-cobalt recovery to produce a copper-cobalt-iron alloy in the cobalt recovery furnace (CRF). The CRF process aims to obtain a final slag of approximately 0.4% copper and 0.2% cobalt which is normally discarded. The reductant used in these two processes is coke. The CRF process is intended to maximize the recovery of copper and
