Magnetic Separation: Magnetic separation is a process of concentrating the desired material by the use of a magnetic field. In the context of copper extraction, this method is employed to separate iron sulfides from copper sulfides. The crushed and ground ore is then taken through a magnetic separator which has strong magnetic fields.
