In the following, each of the three operations, the organic leach, the solvent extraction, and the stripping will be discussed and described in more detail.
Principle: This method is used when either the ore or the impurities are magnetic in nature; Example: Concentration of Iron Ore using Magnetic Separation: Iron ore is magnetic, while the gangue particles are non-magnetic. A magnet is used to separate the magnetic particles from the non-magnetic ones. Magnet: Used to attract the magnetic particles.
