    processes. Copper pyrites are the main ores used for extracting copper. The copper ore is first roasted to drive out the water, CO2 and sulphur. It is followed by melting in a reverberatory furnace of the type used for wrought iron. Silica is added to the charge to form slag with impurities like iron and alumina, etc. The molten metal is tapped and transferred to a convertor where air is blown ...

  • How copper is made

    The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased. Some of these steps are conducted at the mine site itself, while others may be conducted at separate ...
