Manganese Ore processing
Manganese ore processing mainly includes crushing, washing, gravity separation, magnetic separation and flotation processes, etc. After beneficiation, the ore becomes more valuable and can be used in various industries such as steelmaking and alloys.
Application: beneficiation of the manganese oxide ore, carbonate manganese ore, manganese-containing iron ore and multi-metal composite manganese ore.
manganese Beneficiation Process
Manganese ore beneficiation is extracting valuable minerals and removing impurities from manganese ore. It usually includes crushing, grinding, washing, gravity separation, flotation or magnetic separation to improve the grade and concentration of manganese. The manganese ore process is used to beneficiate manganese oxide and carbonate ore.
- Pre-separation: usually includes crushing and grinding to reduce the size of the ore particles; sometimes a washing process is also used to effectively remove impurities such as soil and clay adhering to the surface of the manganese ore.
- Gravity separation: A method of using gravity differences to separate and enrich manganese minerals in ores; usually suitable for situations where the density difference between manganese minerals and waste rocks is large. Its equipment includes jig separators, shaking tables, spiral chutes, etc.
- Magnetic separation: It mainly separates the manganese iron oxide. Manganese minerals are attracted to magnetic fields, while impurities are not.
- Flotation process: Flotation separates manganese ore by adding chemicals to make the surface of manganese ore particles hydrophilic or hydrophobic. It mainly beneficiates manganese ores containing non-metallic impurities such as silicates.
Usually, the combined beneficiation process is used for manganese ore processing plant according to the characteristics of the ore, maximize the mineral grade and recovery rate. Contact us to get more manganese ore process details and equipment price!
manganese ore Processing plant
1. Rock Manganese Ore Processing
This setup is for the rock manganese ore processing plant, main equipment and flow including:
- The raw bin+vibration feeder for feeding materials to the jaw crusher automatically, you only need to load the materials to the raw bin by truck or excavator or else as you want.
- The jaw crusher is for crushing the raw ore to small pieces, then to the cone crusher to get the fine sizes. The vibration screen for separating the size +20mm back to the cone crusher, 0-20mm will sent to ball mill by electromagnetic feeder.
- The ball mill is for grinding the 0-20mm materials to 0-1mm, then using the slurry pump to transport the 0-1mm materials to the spiral chute to separate the heavy minerals.
- The double drum magnetic separator is for separating the manganese from other heavy minerals, making the manganese concentrate to a higher grade.
2. Alluvial & Rock Manganese beneficiation
This setup is one 30tph alluvial and rock manganese ore processing plant, the main equipment and process details as follows:
(1). The raw ore is fed into the hopper by an excavator, with a vibrating feeder (with a 75mm gap grid) under the hopper. Morethan 75mmmaterial are directly transported by a belt conveyor to the hopper in front of the crusher.
(2). The materials smaller than 75mm are evenly fed into the trommel scrubber to wash the sticky clay. The rotary scrubberhas 2 layers of screens (mesh 2mm and 20mm). It can screen out three different sizes: 0-2mm, 2-20mm. 20-75mm.
(3). The content of the 0-2mm part is about 33%, which directly enters the 1st and 2nd jig separators for sorting. The concentrate from the jigseparatorwill enter the two drum magnetic separators to refine manganese again.
(4). The content of the 2-20mm part is also about 33%, which is fed into the 3rd and 4th jigs for re-selection with a connecting steel chute.The larger 20-75mm size is transported to the hopper before the crusher and mixed with particles > 75mm. Below the hopper, a trough feeder is used to feed the material into a jaw crusher to be crushed into material less than 40mm; then it is transported to two hammer crushers for fine crushing. The discharge will be pumped to the 5th and 6th jigs by a mud pump.
(5). The concentrate produced by the jig will enter two drum magnetic separators to refine the manganese concentrate again. The tailings produced by the jig and magnetic separator will enter the tailings pond and can be transported away by a mud pump.
