What is the sulphide ore of copper?

Similarly, how is copper extracted from sulphide ore? 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. The obtained metal is then purified by electrolytic refining.
