Copper can be extracted from its ore by heating it with carbon. Impure copper is purified by electrolysis in which the anode is impure copper, the cathode is pure copper, and the electrolyte is copper sulphate solution. An alloy is a mixture of two elements, one of which is a metal. Alloys often have more useful properties than the metals they contain. Extraction and purification of copper
