extraction of copper from copper sulphide ore

  • How is Copper Extracted from Its Sulphide Ore? Explain the

    Copper is a metal that is present low in the reactivity series. It mainly occurs in nature in the form of sulphide ore which can be converted into the corresponding oxide simply by heating in the absence of air, a process known as roasting.
