Process Flow Diagram Of Manganese Beneficiation
    The vast majority of China's manganese mines are depleted, needing for beneficiation processing. However, since the majority of manganese ore is fine-grained or fine cloth inlay, and a considerable number of high-phosphorus, high-iron and a total (with) The useful metals, mineral processing, therefore to the great difficulty of processing. At present, the commonly used method of manganese ore-dressing machinery election (including washing, sieving, and flotation re-election), and the Enrichment of fire and chemical manganese election law,etc.
1.Washing And Screening
    Washing water washing or using additional mechanical scrubbing to make the separation of ore and clay. Commonly used screen washing equipment, washing machine drum washing machine and trough washing machine. Washing and screening operations often accompanied, as in the shaker directly flush cleaning or washing machine to obtain the ore mining (net mine) before sieving shaker. Screening can be used as an independent operation, the separation of different size and quality supply of products used for different purposes.
2.Re-Election
    The current re-election only for sorting simple structure, embedded coarse cloth of the manganese ore particle size, especially for high density manganese oxide. Commonly used methods are heavy-medium beneficiation, ore beneficiation and shak er beneficiation.
    At present, process flow treating m anganese oxide in China , the general is broken ore to 6 ~ 0mm or 10 ~ 0mm, and then grouped to carry out rough level jigging, small levels of the election to send shaker. Equipment for the Haz-style-type reciprocating jig and 6-S-type shaker.
.High Intensity Magnetic Separation
    Manganese complex is a weak magnetic minerals (magnetization than the coefficient X = 10X10-6 ~ ~ 600X10-6cm3 / g), in the magnetic field strength Ho = 800 ~ 1600ka / m (10000 ~ 20000oe) magnetic separator of the strong magnetic field can be recovered, can improve the grade of Manganese by 4% ~ 10%.
    As a result of the operation of magnetic separator is simple, easy to control, the application can be used for a variety of strong sorting manganese ore, manganese ore-dressing in recent years have been dominant. All kinds of new type of rough, medium and fine-grained magnetic machine being developed. At present, the domestic application of manganese is the most common medium-grained intensity magnetic separator, coarse-grained and fine-grained strong magnetic separator is gradually applied, micro-fine strong magnetic separator is still in the testing stage.
4.Re– Magnetic
    At present, construction work and alterations have been re - magnetic separation plants include Fujian Lian cheng, Guangxi Longtou , Jingxi and Xialei manganese mines. Such as Liancheng manganese re - magnetic separation plant, which mainly deals with the leaching-type manganese oxide, the use of AM-30-type jig to deal with the 30 ~ 3mm washed ore, manganese availability and quality for more than 40% of manganese ore, Impurity election after re-handling, can be used as raw material powder of manganese batteries. Jig tailings and less than 3mm diameter washed mine after grinding to less than 1m, with strong magnetic sorting machine, manganese ore grade of 24 percent to improve to 25% to 36% ~ 40%.
5.Magnetic – Flotation
    At present, only Magnetic - Zunyi uses manganese flotation. The Mine is mainly of low manganese carbonate manganese, low-phosphorus, manganese high-speed rail.
    According to industry tests, the use of grinding rod mill processes - grinding milling stage, equipment size 2100mmX3000mm are wet grinding machine. Strong magnetic separation using magnetic shp-2000-type machine, mainly used flotator CHF flotator inflatable type. After years of production tests, good performance, it is suitable for the application of Zunyi manganese ore beneficiation. Magnetic - flotation process successfully tested and applied in production, indicates that the manganese had been deep-election a big step forward.
6.Enrichment Of Fire
    Manganese Ore Enrichment fire to deal with high-phosphorus, high-speed rail Refractory Manganese ore depleted a sorting method, commonly referred to as manganese-rich slag method. Its essence is the use of manganese, phosphorus, iron reduction temperature is different in the blast furnace or electric furnace to control the temperature selective separation of manganese, phosphorus, iron sorting method of a high temperature.
    Enrichment of the fire process is simple, production stability, and to be effective in iron ore, phosphate isolated, and access to rich manganese, low iron, low-phosphorus manganese-rich slag, the manganese-rich slag containing general Mn35% ~ 45%, Mn/Fe12 ~ 38, P / Mn <0.002, is a high-quality manganese alloy materials, but also the general natural Mn-rich at the same time it is very difficult to achieve the above-mentioned three indicators of man-made rich. Therefore, the enrichment of fire for the high-speed railway in China with low phosphorus manganese ore dressing difficult, it is a promising method of beneficiation.
7.Chemical Manganese Election Law
    There are many c hemical beneficiation of manganese, China carried out a great deal of research, which tests are more, followings are more promising : dithionite method , black manganese method and manganese bacteria leaching method. They have not yet been put into industrial production.
