Smelting the Ore Historical Marker

Copper concentrates were "roasted" in furnaces to remove part of the sulphur. Roasted concentrates were then smelted in a blast or reverberatory furnace to further remove impurities. This process formed molten copper matte and slag, a waste material made up of iron oxide and silica (sand).
