  23.2: Principles of Extractive Metallurgy

  202475 · Solution 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 oxide is then reduced with carbon or any other suitable reducing agent to …
