The Bureau of Mines conducted bench- and small-scale continuous studies to develop a process for recovering a recyclable copper product from waste, granulated, blast furnace slag. The investigation was part of the Bureau's secondary resource recovery program. The slag contained 5 to 7 percent total copper, of which 3 to 4.5 percent was metallic copper.

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.
