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.
Introduction:
Jigging machine of 2LTC-6109/8T is widely used in mineral dressing or beneficiation system for kinds of ores like hematite, limonite, sand gold ore, manganese ore, tungsten ore, tin ore, Ta-Nb mineral, mercury ore, fluorite ore, barite ore, the azure quarries and so on. It can be also used to recovery metals or alloy particles from kinds of smelting slag like silica-manganese slag, ferro-manganese slag, nickel slag, steel iron slag, sulfate slag.
Working principle:
2LTC-6109/8T jigger is kind of side-moving rectangle jigger with two rows and four chambers. Motor drives reduction gears moving by the transmission. There are eccentric adjusting devices at both output ends of the reduction gears. The eccentric adjusting device drive the connecting rod after adjusting to drive the driving pan to do the alternation motion extruding the liquid in the cell body and promoting waves. The waving water moves through the screen to impact the ore on the screen making the ore in the state of free-failing body in the liquid. The ore grains own different dropping speed in the liquid because of the different density, so the ore will separate naturally. Finally, the heavier ore will be discharged out of the cell body after the adjustment and the lighter ore floats the waste-discharging mouth to be discharged and the whole ore beneficiation process is finished.
Advantages:
1. Energy-saving, high enrichment efficiency and environmental-friendly.
2. Trapezoid Working area, high recovery rate, and large handling capacity.
3. Eight jig dressing chambers, adjustable stroke and stroke frequency for each slot, wide range of selected particle size.
4. High stability, simple operation, convenient maintenance
