In production practice, wolframite ore beneficiation equipment is mainly based on the wolframite beneficiation process. Generally, the common wolframite beneficiation process mainly includes: roughing, grinding, gravity separation, concentration and fine mud treatment. stage. The following editor will introduce the relevant black tungsten ore beneficiation equipment around these mineral processing processes.

1. Wolframite roughing equipment

The wolframite roughing equipment mainly focuses on crushing, screening, feeding and belt transportation. Roughing is the pre-enrichment of wolframite. According to the collection method, the raw ore is crushed to a certain extent by the crusher, and then fed into the screening machine by the feeder for screening, and then sent to the next stage via the belt conveyor Or it can be returned to the crushing stage for re-crushing. During the transportation process, manual selection operations will be set up to select some qualified wolframite ores in advance to improve the efficiency of tungsten ore selection.

The main wolframite roughing equipment includes:Crusher, circular vibrating screen, belt conveyor and feeder.

2. Wolframite grinding equipment

The wolframite grinding equipment is mainly used to further finely grind the coarsely selected tungsten ore particles to achieve monomer decomposition between minerals. separation to provide materials for subsequent sorting operations. Because tungsten is brittle and has a large specific gravity, it is prone to over-crushing during the grinding process. Therefore, rod mill equipment is mainly used to complete the grinding operation. The process requires one stage of grinding and one stage of rod mill+ based on the properties of wolframite ore. Medium ore grinding or two-stage grinding process.

The main wolframite grinding equipment is: Wet rod mill, lattice ball mill, spiral classifier, hydrocyclone, etc.

3. Wolframite gravity separation equipment

Wolframite gravity separation is the main means of tungsten separation. Generally, multi-stage jigging and multi-stage shaking table separation are used. The fine mud obtained is processed centrally to obtain coarse concentrate. Among them, the coarse and medium-grained jig tailings are fed into the rod mill for re-grinding, and the ground products are returned to the double-layer vibrating screen, forming a closed loop. Shaking tables usually use two separations. The coarse and medium-grained shaking tables return the ore to the circulation loop, and the slime is processed separately. The main wolframite gravity separation equipment includes: jig and shaker.

Jig: Screen qualified ore into three levels: coarse, medium and fine. Entering the jigging operation, the coarse-grained jigging particle size is generally 8-10mm, and the medium-grained jigging particle size range is 1.5-5.mm.

Shaking table: Mainly responsible for the separation of fine-grained minerals (suitable particle size is 0.037-2mm). Generally, two operations are performed. The coarse and medium-grained shaking tables return the middle minerals to the cycle. loop, and the sludge is processed separately.

4. Wolframite beneficiation equipment

Selection is mainly to re-separate the roughly selected minerals, because the roughly selected wolframite ore still contains a small amount of Valuable metal ores such as tin, molybdenum, bismuth, copper, and zinc need to be selected through flotation, magnetic separation and other methods to obtain fine-grained wolframite concentrate. The equipment required is mainly: magnetic separation equipment and flotation equipment.

Magnetic separator equipment: Dry magnetic separator can be used, the processing particle size is 0.074-3mm, magnetic separation Afterwards, purer tungsten concentrate can be obtained, but the tailings contain high tungsten and require multiple sweeps.

Flotation equipment: Mainly uses Taiwan flotation machine, which can achieve flotation separation of easy-to-float sulfide and other minerals through flotation.

5. Wolframite fine mud treatment equipment

The main function of the wolframite fine mud treatment equipment is to first desulfurize the tungsten fine mud, and then use gravity separation according to the properties of the fine mud. , flotation, magnetic separation, electric separation and other methods to recover wolframite ore.

The main equipment at this stage includes: gravity separation equipment (jigs, shakers, centrifugal concentrators), flotation machines (XCF, KYF, SF, JJF flotation machines), magnetic separators (dry type magnetic separator, wet magnetic separator, permanent magnet drum type magnetic separator).

The above is the equipment commonly used in wolframite beneficiation plants. In actual beneficiation plants, it also needs to be determined according to the properties of wolframite ore and the Process design and equipment selection are required for other mineral types contained, so it is recommended to design a suitable mineral processing process through mineral processing test analysis. If you have any needs, please feel free to consult Xinhai Mining Equipment, which can help you design the mineral processing process, the construction plan of the mineral processing plant and the complete set of tungsten ore mineral processing equipment.
