The beneficiation methods of manganese ore include gravity beneficiation method, magnetic separation method and flotation method, but the most widely used one is gravity beneficiation method. Gravity beneficiation method can purify most of manganese oxide ore and part of manganese carbonate ore, it has the advantages of small investment, high efficiency, low energy consumption and no pollution, it is the most ideal beneficiation method for manganese ore.
Manganese ore gravity beneficiation production line is mainly composed of crusher, vibrating screen, washing machine, jig machine, dewatering screen and other equipment. The raw ore enters the jaw crusher for coarse crushing, and then enters the secondary crushing. According to the size of the beneficiation plant, we can use jaw crusher or cone crusher as secondary crushing, and the finely crushed manganese ore goes into circular vibrating screen for screening. The screened material is sent to the jigger for gravity beneficiation, and the jigger separates manganese ore and veinstone, and finally gets concentrate and tailings, and the concentrate and tailings are transported to the destination site for stockpiling after dewatering respectively. For manganese ore with large mud content, it is also necessary to add washing process before the crushing process. Manganese ore washing generally adopts trommel scrubber or double spiral washing machine.
