Hematite Iron Dry Magnetic Separator

Similar to limonite iron ore, hematite is kind of weak magnetic iron ore with the similar beneficiation method-gravity separation, intensity magnetic separation, magnetizing roasting process during which the most common beneficiation way is gravity separation. For dry upgrading of hematite, only the intensity magnetic separation can work. Here is some share about this kind of intensity magnetic separator for hematite upgrading.

Actually, intensity magnetic separation is kind of dry concentration method for hematite, but not all hematite can be upgraded by this method. There are two items needing to be met for hematite intensity magnetic separation:

1. there is obvious parting line between hematite and gangue with the inlay size of 0.5-5mm. The liberation or dissociation of hematite grains can be realized through crushing, screening, or even milling.

2. The hematite shall be magneto conductive. Most iron has magneto conductivity while for hematite, the magneto conductivity is very weak and only intensity magnetic separator can attract the hematite granules. However, for some hematite of serious oxidization, even magnetism of 15000Gauss can not get the hematite.

In real hematite processing project, hematite upgraded by magnetic separation can also be upgraded by gravity separation. But for places of rare-water, intensity magnetic separator can be used while gravity separation will be limited by its water consumption. Intensity magnetic separation needs no water to work, but its treatment capacity is small and the plant investment is high with lower efficiency and lower beneficiation indexes. So for hematite iron ore beneficiation, if condition permits, gravity separation can be adopted optimizing to magnetic separation.

The dry magnetic separator for hematite is as below:

Forui intensity magnetic separator adopts high-quality Nd-Fe-B magnet. The magnet has been assembled to form intensity magnetism of 15000 Gauss and this magnetic separator can used in dry separation or beneficiation of iron ore, manganese ore, garnet ore, etc. This magnetic separator has its own feeding device, speed-adjustment device and dust-removing device, and it is very easy to operate.
