Electromagnetic separation of silicon from
Zhou et al. [26] proposed a combined technology of electromagnetic separation and slag treatment to treat MGSRS; this method requires the addition of a calcium silicate slag containing chlorine, and is therefore characterized as slag refining. However, these methods either require an additive or have a low recovery rate.

Electromagnetic separation is used in the concentration of:
Electromagnetic separation is the method to concentrate the ore or to remove unwanted materials like sand and clay from the ore. Magnetic or electromagnetic separation is the technique based on differences in magnetic properties of the ore or gangue. The particles that are attracted with the magnetic field are separated out.

Methods of concentration of Ores – Gravity Separation.
Electromagnetic separation; As the name suggests, magnetised material, such as a magnet-equipped roller, is used for separating the unwanted particles to enrich the ore. The magnetic characteristics of the ore or the gangue particles are used for separation. The ore is powdered and is laid on a conveyor belt that passes through a magnetic roller.
