In this method, the ore is poured over a sloping and vibrating corrugated table with grooves and a jet of water is allowed to flow over it. The denser ore particles settle down in the grooves and lighter gangue particles are washed down by water. b) Magnetic Separation. The Principle of magnetic separation is magnetic properties of the ores.

A lot of energy is needed to reduce them to extract the metal. • The oxides of lesser reactive metals, such as iron, form less stable oxides and other compounds. Relatively little energy is needed to reduce them to extract the metal. So, the method of extraction of a metal from its ore depends on the metal's position in the reactivity series.
What are the 3 methods of extracting metals? There are 3 main methods of extracting metals from their ore. They are reduction of the ore with carbon, reduction of the molten ore by electrolysis, and reduction of the ore with a more reactive metal. What method is used to extract copper from its ore? Copper is purified by electrolysis.
