A BRIEF REVIEW ON BLAST-FURNACE SLAG AND COPPER

of copper is produced, 2.2-3 tonnes of CS are gen-erated [4]. In Oman approximately 60,000 tonnes of copper slag is produced every year [5]. The pro-duction approximately 0.36, 0.244, 2.0, and 4.0 million tonnes of CS is reported in Iran, Brazil, Ja-pan and the United States, respectively [6]. Cur-rently, about 2 million tonnes of waste copper slag

12.3 Primary Copper Smelting

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.
