Manganese Ore Magnetic Separator

Gravity separation and magnetic separation can be involved for manganese upgrading. Gravity separation is more commonly used in manganese beneficiation with its low plant investment and low operation cost. However for some manganese ore of too fine inlay or small density difference between manganese and its attached gangue, gravity separation can not work, magnetic separation or floatation separation can be considered. In this situation, magnetic separation can be the main beneficiation way for manganese ore because floatation separation needs large investment and high operation cost and it is hard to be accepted by the miner. Intensity magnetic separation can be the core upgrading method for this kind of manganese ore. The following is about Forui manganese magnetic separator.

Manganese magnetic separator is actually dry type intensity magnetic separator with its magnet of high-quality NdFeB magnetic material installed in a special order to reach magnetism intensity of 12000-16000Gauss. For weak magnetic ores like manganese, hematite, limonite, specularite, garnet, this intensity magnetic separator can help to get high grade concentrate with high recovery. There is feeding device, frequency control device, and dust-removing device on this magnetic separator. It needs small area to work with high treatment capacity, no pollution to environment and good beneficiation efficiency.


 The following table is parameters about the manganese ore intensity magnetic separator:

Model	Magnetism Intensity (Gs)	Feeding size (mm)	Handling capacity (T/h)	Feeding power (KW)	Main power (KW)
CTG160*800	12000-16000	<5	4-6	0.2	1.1*2
CTG160*1200	12000-16000	<5	6-8	0.4	1.5*2
CTG160*1500	12000-16000	<5	8-10	0.4	2.2*2

The following is about the photogram of measurement about magnetism of manganese magnetic separator. (PS: 1.2T=12000 GAUSS)

 

The following picture is about manganese ore test. This manganese ore is hard to upgrade by gravity separation and magnetic separation can be used to get ideal beneficiation efficiency. The upper one is the raw manganese ore, the bottom left picture is the tailings after magnetic separation while the bottom right one is about the manganese concentrate after intensity magnetic separation:

Gongyi Forui Machinery Factory is professional manufacturer of kinds of mining machinery, and has rich beneficiation experience about manganese dressing. Forui manganese jigging separation machines and manganese magnetic separator has been used widely. Test can be done for you if samples can be available, and flow sheet with plant details can be designed for you according to the test.
