This present paper discusses both the dry and wet magnetic separation techniques used for processing of a low grade siliceous iron ore sample. 2. Materials and methods. About 500 kg of a low grade siliceous iron ore sample was crushed to below 10 mm size by using jaw crusher. The crushed sample was thoroughly mixed and subjected for sampling by

### Magnetic Separation and Iron Ore Beneficiation IspatGuru

Oct 04, 2018Magnetic Separation and Iron Ore Beneficiation Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

### Magnetic separation

Weak magnetic separation. Weak magnetic separation is used to create cleaner iron rich products that can be reused. These products have low levels of impurities and a high iron load. This technique is used as a recycling technology. It is coupled with steelmaking slag fines as well as a

### PURIFICATION OF IRON ORE (BY MAGNETIC SEPARATION METHOD

PURIFICATION OF IRON ORE (BY MAGNETIC SEPARATION METHOD) It may be called the king of metals. The Ore of Iron can easily be separated from Gangue by this method. Large amount of ore can be purified by this method. It has two rollers, one is magnetic roller other one is nonmagnetic roller. When ore is dropped on the magnetic roller,

### Industrial Separator Magnets Walker Magnetics

Separator Magnets. Walker engineers and manufactures magnetic pulleys, drums, suspended magnetic separators, and eddy current separators designed for beneficiation, tramp iron removal, non ferrous metal recovery and various other separation processing applications.

### Maximizing the recovery of fine iron ore using magnetic

The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron ore operation that introduced beneficiation of fine

### Iron Ore Mineral Technologies

The inclusion of medium intensity magnetic drum separation (MIMS) in combination with jigging may be considered for the beneficiation of the 6 1mm fraction of some friable ore bodies. The following diagram demonstrates some typical flowsheet designs for Iron Ore beneficiation of hard rock and friable ores.

### Developments in the physical separation of iron ore

The ore is mainly composed of magnetite, hematite, martite, and quartz. It is very difficult to produce a high quality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% 75 m.
