  •  Primary Copper Smelting

    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.

    minimised (iron losses are one of the major costs in HM desulphurisation). Slag viscosity has a major impact on the iron losses. Too high viscosity leads to iron being entrapped in the slag in emulsion ("emulsion loss"). Too low viscosity means it is difficult to remove the slag, which leads to iron being removed as well ("entrainment ...

    How iron is made

    The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purifiion is slag, which is produced in huge amounts.

     · 1. The role of silica in the extraction of copper is to remove the iron oxide obtained during the process of roasting as slag. If the sulphide ore of copper contains iron, the silica (SiO 2) is added as flux before roasting. Then, FeO combines with silica to form iron silie, FeSiO 3 (Slag). 2.
