Manganese ore separation equipment introduce：

1、 Manganese ore separation method

The vast majority of manganese ore in China belongs to lean ore and must be beneficiated. However, due to the fact that most manganese ores are fine particles or embedded with fine particles, and there is a considerable amount of high phosphate ore. High speed railway mines and co generated beneficial metals bring great difficulties to mineral processing. The commonly used methods for manganese ore separation currently include ore washing, screening, gravity separation, magnetic separation, and flotation.

2、 Process flow of manganese ore separation equipment production line

Manganese ore generally does not use a single separation method, but instead uses combined separation processes such as ore washing gravity magnetic separation, gravity flotation, magnetic separation flotation, etc. For simple manganese oxide ore, washing gravity separation is generally the main method. The manganese ore truck is pulled to the mine, and the ore is generally below 35050mm. The ore bin is stacked by a loader and transported by a belt conveyor. The jaw crusher is transported to the vibrating screen through a belt conveyor. Sieve for sizes ranging from 10mm to 10mm and above. The ore below the screen (10mm~0) is sent to the separation warehouse through a belt conveyor, and the ore above the screen (10mm or more) is sent back to the jaw crusher through a belt conveyor. After screening, the ore particle size is controlled below 10mm and enters the separation warehouse. If further crushing is required, it can be used.

1. Ore washing and screening.

Ore washing is the use of hydraulic flushing or additional mechanical scrubbing to separate ore from mud. The ore washing operation is usually accompanied by screening, such as washing directly on the vibrating screen or sending the ore sand (clean ore) obtained by the washing machine to the vibrating screen for screening. Screening can be used as an independent operation for separating products of different particle sizes and grades for different purposes.

The commonly used equipment for manganese ore separation in this process includes a washing screen, a cylindrical washing machine, and a trough washing machine.

2. Reseparation

At present, it is only used to select manganese ore with simple structure and coarse embedded particle size, especially suitable for high-density manganese oxide ore. The commonly used methods include heavy medium separation, jigging separation, and shaker separation. At present, the treatment process of manganese oxide ore in China generally involves crushing the ore to 6-0mm or 10-0mm, grouping it into groups, skipping the coarse grade, and selecting a fine grade shaking table.

The commonly used equipment for manganese ore separation in this process mainly includes jigs and 6-S shakers.

3. Magnetic separation/strong magnetic separation.

Manganese ore is a weakly magnetic mineral with a specific magnetization coefficient of x=1010-6~60010-6cm3/g and a magnetic field strength of ho=800~1600ka/m (1000~20000oe). The magnetic separator can be recycled and can generally increase the manganese grade by 4% to 10%. Due to its simple operation, convenient control, and strong adaptability, magnetic separation can be used for the separation of various manganese ores, and has dominated the separation of manganese ores in recent years. Various new types of coarse, medium, and fine grain strong magnetic machines have been successfully developed.

At present, medium to high strength magnetic separators are widely used in manganese ore magnetic separation equipment in China, while coarse to high strength magnetic separators are gradually being applied, while particle high strength magnetic separators are still in the experimental stage.

4. Gravity magnetic separation.

Mainly processing filtered manganese oxide ore, using AM-30 skip machine to process 30-3mm cleaning ore can obtain high-quality manganese concentrate containing over 40% manganese, and then manually selecting impurities for removal, which can be used as a raw material for battery manganese powder. After cleaning the tailings and ore stems below 3mm to a depth of less than 1m, a strong magnetic selector is used to select the manganese concentrate, which increases the grade by 24% -25% and reaches 36% -40%.

5. Strong magnetic flotation.

Manganese carbonate ore is mainly used for low manganese, low phosphorus and high iron manganese ores. According to industrial experiments, the grinding process adopts the stage of rod and ball grinding, and the equipment scale is φ 2100mm 300mm wet grinding machine. The SHP-2000 strong magnetic machine is used for strong magnetic separation, while the CHF inflatable flotation machine is mainly used for flotation machines. After years of production testing, the performance is good. The successful application of the strong magnetic flotation process test in production marks a significant step forward in China's manganese ore deep separation.
