Crushing line of manganese ore
Under the manganese industry policy of "looking for rich ore, getting rich from poor, and deep processing", the crushing processing and beneficiation technology of manganese ore in domestic has developed rapidly. Relying on the progress of science and technology, the development and utilization of manganese resources have developed towards the direction of deep processing and fine processing, and a fairly mature production scale has been formed. The finished products have entered the international market in large quantities, so the prospect of investment in manganese ores is very broad. However, most manganese ores in domestic belong to lean ores and must be beneficiated. However, because most manganese ores are fine or embedded with fine particles, and there are a considerable number of high phosphate ores, high iron ores and co (concomitant) beneficial metals, it is very difficult to beneficiate. SMMVIK, the domestic provider of mining crushing solutions, provides you with a full set of manganese ore crushing processing and production equipment, and provides you with detailed technical support.
Processing technology
At present, the technological process of processing oxidized manganese ore in domestic mainly includes three processes: crushing, grinding and beneficiation. Generally, the ore is crushed to 6~0mm or 10~0mm, and then grouped. The coarse grade ore is eliminated, and the fine grade ore is sent to the shaking table for beneficiation. At present, the commonly used crushing equipment is the jaw crusher. After the crushed manganese ore is grinded into finished products of various specifications by the vertical pendulum mill, the appropriate beneficiation process is used for beneficiation.
Stage I: crushing and screening - three-stage closed circuit crushing
The large manganese ore is uniformly sent into the jaw crusher or the coarse crushing mobile station for coarse crushing by the vibrating feeder through the bin; After coarse crushed manganese ore is screened by vibrating screen, it is sent to single cylinder hydraulic cone crusher by belt conveyor for intermediate crushing; The manganese ore after medium crushing is sent to the multi cylinder hydraulic cone crusher for fine crushing;
Stage II: Grinding
The 0-12 mm manganese powder screened by the vibrating screen is uniformly sent to the mill for grinding, and is screened by the spiral classifier. The unqualified manganese powder is sent to the mill for further grinding;
The third stage: beneficiation
The manganese powder meeting the requirements of mineral processing is sent to the magnetic separator for high intensity magnetic separation to remove impurities, and the manganese powder obtained is sent to the dryer for drying to obtain manganese concentrate.
