Magnetic separation has two major applications in mineral processing plants The removal of tramp iron (which would deleteriously affect subsequent processes) from an ore stream. This is usually achieved by a low intensity magnet suspended above, or at the head of, a conveyor. Separation of magnetic minerals from less magnetic minerals.
Concentration of minerals is performed by means of a series of consecutive operations, which constitute the enrichment program. The initial operation is crushing and pulverization of the raw material to reduce it to a particle size that is suitable for existing concentration processes and equipment, as well as for the separation of concretions and formation of particles of individual minerals.
Magnetic Concentration. a method for separating minerals from waste rock and undesirable impurities. The method is based on the action of a magnetic field on mineral particles with various levels of magnetic susceptibility. The first magnetic separators date to the 18th century; the perfection and industrial use of the method date to 1892 1906
Concentration of Minerals Minerals often need to be concentrated before metallurgical processes. The concentration can be done by flotation, magnetic and gravity separation or pre reduction due to the nature and composition of the mineral.
Classification of minerals on the magnetic properties Strongly magnetic minerals franklinite, maghemite, magnetite, pyrrhotite ( monoclinic ), titanomagnetite
Concentration or dressing of the ore The ore are usually obtained from the By magnetic separation method the nonmagnetic minerals is separated from the Magnetic separation Magnetic separation is a process in which magnetically susceptible material is extracted from a Cornwall or with bismuth such as at the Shepherd and Murphy mine in .
Other major monazite sources are heavy mineral sands from so called placerdeposits which are usually mined by dredging or scraping, followed by screening and concentration in spiral concentrators. Mineral concentrates are then washed, dried and fed into magnetic separators to remove e.g. ilmenite and other magnetic minerals.

In some cases, chromite concentrates can be produced by wet gravity concentration alone. In other chromite beneficiation processes, magnetic separation by RED is an essential polishing step. Figure 3 shows a typical flowsheet for upgrading chromite where gravity concentration is followed by dry magnetic separation.
Concentration. Concentration is defined as the number of moles of a solute in a volume of the solution. In case of mineral processing concentration means the increase of the percentage of the valuable mineral in the concentrate.
