As the iron ore minerals are liberated by the crushing steps, the iron-bearing particles must be concentrated. Because only about 33 percent of the crude taconite becomes a shippable product for iron making, a large amount of gangue is generated. Magnetic separation and flotation are the most commonly used methods for concentrating taconite ore
2 Description of industrial magnetic separation process The Golgohar ore body is located in southeast Iran, which contains half billion tons of ore having about 42% iron. Golgohar Mining and Industrial Company operates six separated ore bodies of Golgohar. It produces 10.8 million tons of iron ore concentrate, 157 thousand tons of ne iron

Magnetic separation is a recognised technique in the bulk handling industry and has been for many years. A magnetic separator is an industrial tool which creates a powerful magnetic field. It is traditionally used to protect conveyors or other valuable equipment further down the line from tramp iron damage, contributing to less downtime

magnetic separators and the principal ferromagnetic mineral separated is magnetite (Fe304),although hematite (re203) and siderite (FeCO3) can be roasted to produce magnetite and hence give good separation. The removal of tramp iron from ores can also be regarded as a form of low-intensity magnetic separation
