China's manganese oxide ore is mostly secondary manganese cap type, weathered leaching type and stacked type deposit. In the past, this type of ore was only subjected to simple washing treatment. With the development of new technologies and equipment, it is mainly used in the process of washing and re-selecting, washing a strong magnetic process or washing and re-selecting a strong magnetic process. Jingxi Guangxi manganese oxide, manganese ore and manganese ore was soft manganese-based hard gangue minerals are quartz, kaolinite, mica, water; reselection beneficiation plant using a re-election process a strong magnetic separation (see FIG. The Mn content of the selected manganese ore is 37. 02% ~ 48. 43%. The manganese grade of the selected ore concentrate is 34. 22% ~ 38. 86%. The Daxin manganese mine in Guangxi is one of the largest manganese carbonate deposits in China, and its upper part is weathered manganese cap-type manganese oxide ore. The Daxin manganese ore beneficiation plant adopts a process of washing and re-selecting a magnetic separation process. After the ore is washed and jigging, 5~0. 8mm is sorted by CS-2 strong magnetic field magnetic separator, -0. 8mm SHP-1000 strong magnetic field magnetic separator is sorted to obtain battery manganese and metallurgical manganese products. Figure 1 Process flow of manganese oxide ore sorting in Jingxi manganese ore dressing plant Foreign countries mainly rely on washing or re-election for simple manganese oxide ore. The Goupani manganese mine in South Africa uses a hydrocyclone desliming and spiral washing machine sorting process to produce 40% Mn02 concentrate from fines tailings containing 20% ​​Mn02. Brazil's Serra Donavio manganese ore uses two Dina-type vortex cyclones with a diameter of Φ400mm to treat 6-0.8mm of fine ore. The ferrosilicon is used for weighting, and the density is 2800~3200kg/m3. The sorting and heavy medium cycle process is shown in Figure 2.

The final product can be cut as per set length controller,and the length is automatically measured by encoder.When final product reached set length,machine will stop to cut the sheet automatically.Finish thhis action,the machine will run again continuously

Manganese ore re-election
Production of the world's manganese (Mn include iron, silicon manganese, manganese metal, high-quality manganese ore) approximately 90% of the metallurgical industry for the production of steel. The rest are used in light industry, chemical industry, agriculture and other aspects. The manganese-containing minerals in manganese ore mainly include pyrolusite (Mn02, density 4300~5000kg/m3), hard manganese ore (mMn0·Mn02, density 4900~5200kg/m3), and rhombohedral (MnC03, density 3300~3700kg/m3). In addition, a large number of polymetallic manganese nodules are also distributed in the deep ocean. Depending on the natural type of minerals in the ore and associated elements, manganese ore is usually divided into manganese carbonate ore (manganese in carbonate manganese minerals accounts for more than 85% of the ore content of ore) and manganese oxide ore (manganese oxide minerals) Manganese accounts for more than 85% of the ore content of manganese ore, mixed manganese ore and polymetallic manganese ore.
