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.

Zhang et al. [23] studied the process mineralogy of copper ores and found that copper minerals are mainly sulfide minerals that are easily floated, but most of them are embedded at around 0.3 mm, requiring a grinding fineness of 85–90 % −300 mesh to make the copper ore fully dissociated. The study of process mineralogy holds a significant ...
