CHEM

The metal ore is initially melted in a shallow reverberatory furnace and the molten copper is stirred with logs of green wood The blistered copper with cuprous oxide gets reduced to its metallic state by the gases given off by green wood the impurities get removed either in the form of gases such as SO 2 As 2 O 3 etc or they form scum over the molten metal which is then skimmed off
