Manganese exists widely in nature, and it is almost covered for each mineral and silicate stone. The common manganese ore is manganese oxide and manganese carbonate with or without water. There are about 150 kinds of manganese ore, but there is about 5 or 6 ores of rich manganese among which the most important and most economical manganese ores are pyrolusite, psilomelane while the other three are manganite, braunite, hausmannite, rhodochrosite. Askind of important industrial mineral, the Mn content is 50-70% in these ores. 

As kind of weak magnetic ore, the basic beneficiation methods for manganese ore are mainly gravity separation and intensity magnetic separation even though there are many kinds of manganese ores. 

The gravity separators mainly refer to jig separators, and sometimes shaking tables. But considering small handling capacity and feeding size limitation of shaking table, it can not be used in large scale manganese separation. And here jigger is the widely used concentrating machine for manganese ore. Jigger for big blocks ore makes gravity separation more common. Jig works on basis of density difference between useful mineral and gangue with its high efficiency, energy-saving, large feeding size, and environment-friendly.

Manganese ore is kind of weak magnetic mineral and intensity magnetic separator can separate manganese from gangue with its high efficiency. For the fine manganese ore, intensity magnetic separator is usually adopted. There are two kinds of intensity magnetic sepration, one of rough separation and one of scavenging separation. Forui intensity magnetic separator adopts magnet of NdFeB material. There are two manget rollers with intensity magnetism. This separation device can be adjusted and this intensity magnetic separator is the main magneic separator for manganese magnetic separation.

Forui manganese jig separator are mainly for coarse manganese granules separation. Forui jigger of AM30 and 2LTC912/4A jigger can deal with manganese of 10-50mm while jigger of 2LTC6109/8T jigger can deal with +50meshes-10mm. Forui intensity magnetic separator is 15000 Gauss with its feeding size of -5mm, and it can help to gain great magnetic separation efficiency for beneficiation of manganese, hematitem limonite, etc. 

Illustration:
This mineral concentration jigging machine of 2LTC912/4A model is remolded on the foundation design of the original 2LTC-912/4 and AM-75 jig machine. It pertains to double-row & four-chamber & side-plug-fuse type. This model of ore beneficiation jigger can be adoptable for the large size with its large handling capacity.

Superiority:
Overcoming the shortcomings of 2LTC - 912/4 jig's graining processing and AM - 75 jig's difficulty of discharging large quantity, particle size, it is used in the beneficiation of kinds of metals and non-metals of large size.
 
Usage:
Widely used in all kinds of metal mines, metalloid mine, and city construction waste of pretreatment assignments.

Advantages:
1,Energy-saving, high efficiency and environment-friendly.
2,Small occupied area and large handling capacity.
3,Selected wide range and big particle size, Maximum to 50mm.
4,dealing of ore or slag of 30-50mm, with its good selecting efficiency
