Copper Slag Copper slag produced during the matte smelting and refining of copper ore, during which, the iron present in the copper concentrate combines chemically at 1200°C with silica present in flux materials such as river sand/silica sand/ quartz fines to form iron silicate, which is termed as copper slag. The copper slag thus generated is
