    Copper Slag Ap Copper Slag is a by‐product obtained during the matte smelting and refining of copper. It is formed when molten slag is cooled slowly, forming a dense, hard crystalline product. Quick solidification by pouring molten slag into water gives granulated amorphous slag.ISASMELT TM SLAG CHEMISTRY AND COPPER LOSSES IN THE ,When the magnetite content of the RHF slag was less than 7%, it was normal for RHF slag to contain few copper (average 0.7%). When the magnetite content of the slag ex- ceeds 7% the copper content of the slag is variable. The average was 1.1% Cu, but the distribution was broad. These results are illustrated in Figure 8.

  • 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.Utilisation of copper slag for cement manufacture,Table 9: Performance of slag cements prepared by using 35% copper slag at different fineness.
