Advantages of a magnetic separator. Magnetic separators are powerful, portable and can be adjusted to remove various types of magnetic materials from a liquid or solid. They are most effective when used in a liquid, although it is also possible to remove solid impurities. Magnetic separators are very versatile and incredibly simple in design.

Thus, the iron ore was efficiently separated from gangue in magnetic separation [24], [25], [26]. In recent years, many researchers have proved the feasibility of P-SMR technology. They discovered that the phase transform route of iron ore was limonite → hematite → magnetite with an increase of magnetism.

Magnetic separation is a versatile technique used in sample preparation for diagnostic purpose. For such application, an external magnetic field is applied to drive the separation of target entity (e.g. bacteria, viruses, parasites and cancer cells) from a complex raw sample in order to ease the subsequent task(s) for disease diagnosis.

The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes.
