    The three basic refining methods are pyrometallurgical, electrolytic, and chemical. All these methods are based on distinctive properties of the individual elements, such as melting temperature, density, and electronegativity. Pure metals are frequently obtained by employing several refining methods in succession. Pyrometallurgical refining.
