Magnet ore has strong magnetic properties, mainly including single magnet ore, vanadium titanium magnet ore, magnetite and iron oxide mixed ore, magnetite multi-metal symbiotic ore, etc.The magnetite is divided into coarse granules, medium fine particles, fine particles in the magnetite, wherein the iron mine stored in coarse grains and medium fine particles is broken. After the murrization process, it can obtain qualified iron concentrates with a weak magnetic selection process.Micronardized magnet mine needs fine mill to sufficient monomer to achieve better distribution indicators.
The JCTN solution of Walt magnetically developed drainage is a wet magnetic separator for magnetine mine rinsing and purifying design, which is suitable for sorting demeteration of a milling grading overflow product;And the mineral concentration before filtration; the magnetite enters the pre-sieve sieving pre-sieve screened pre-sieve pre-selection before the demetrics; the ultimate selection of magnetite is difficult to improve the fine particles of the routine magnetic option, fine particles ，the iron ore has a significant selection effect.
JCTN Substantuctive Magnetic Separator
Main technical characteristics
■ Binding to the mineral and overflow coincidence is used to achieve the purpose of uniform mine;
■ The use of a new type of sequenceless groove body and the roller reverse rotation can improve the recovery of minerals;
■ A multi-stage rinsing and top water curtain structure are provided in the new sequenceless groove, which can fully rinse minerals on the surface of the drum;
■ Take a 240 ° -270 ° large inclumpar multi-magnetic pole magnetic structure, combined with the magnetic agite in the cartridge, to achieve minerals, roll and magnetic agitation, and under the action of rinse water, sufficiently remove impurities in concentrates, improve Seiko position.
■ The mineral structure is used to achieve concentration of minerals while the mineral structure is used.

Applications
1. Example of a magnetite application in Sichuan
Sichuan magnet mine fine particles, micro-deposited iron ore, the actual production process is a piece of grinding fineness -200 mesh 65%, weak magnetic selection 1500GS coarse selection – 1200GS selection, iron concentrate TFE is 61.24%, and it is only available for more than 1200GS, and the concentrate grade can only be increased to 63.16%, and the recovery of iron is greatly reduced.
Customers require this equipment to be selected for the selected iron coarse concentrate, and investigate the milling of the mill to achieve more than 66% of concentrate quality requirements.
In the test, the concentrate magnetic separator 1200GS was used in TFE grades. The resulting concentrate TFE was 61.83%, and the TFE product was 63.45% in the obtained concentrate.2.55% from 66%.
Take the original concentrate through 160 mesh and 200 mesh screening to analyze the state of the iron.
Table one original mine particle size analysis result
In the particle size analysis, it was found that there were more organisms in the primary iron, and the mortary to -160 was required, iron and vein minerals can achieve sufficient monomer dissociation.Take the original iron refining ore until -160, respectively, the magnetic selection 1200GS and JCTN refine desessment magnetic selection machine 3000 GS magnetic segments are compared, and the test results are as follows:
Table two mill mine magnetic selection comparison results
| Experimental conditions | Product name | Yield% | TFE taste% | TFE recovery rate% |
| -160 Mesh Regular Magnetic Separator1200Gs | Iron concentrate | 88.45 | 65.32 | 94.14 |
| Tailings | 11.55 | 31.17 | 5.86 | |
| Original mine | 100.00 | 61.38 | 100.00 | |
| -160 Mesh JCTN-3000Gs | Iron concentrate | 88.19 | 68.60 | 97.67 |
| Tailings | 11.81 | 12.23 | 2.33 | |
| Original mine | 100.00 | 61.94 | 100.00 |
The original thickness grinding to -160 is 65.32% of the concentrate TFE. JCTN is selected from 68.60%, and the grade and recovery rate is 3.28% and 3.50%, respectively.
In response to the nature of the fine lamination of a magnet mine in Sichuan, the trial determined – coarse selection – Coarse re-grinding – JCTN Substance Damage magnetic optional process is applied in actual production, currently, the distribution plant.The magnetic optional concentrate TFE taste is stable above 68%, and the recovery is similar to the test indicator, and the customer’s high praise.
