iron oxide magnetic separator quartzite process for the benefits

Fine disseminated ore is refractory oxide materials. Many countries in the world on their economies process were studied in detail, mainly magnetic separation, magnetic than roasting, flotation

, Re-election and joint processing methods. Compared with the magnetic separation process, the use of combined iron ore beneficiation process can improve the grade of 2-3% for ore metal recoveries increased by 3-5%. By the

In the oxidation of hydrogen iron ore tube magnet flotation is difficult, therefore, it is only the iron oxide ore hydroxide is discharged from the process in order to successfully using magnetic - floating

Processes. In the above situation can be achieved by pre-magnetic.

    For sorting fine disseminated oxide ore, the magnetic separation process most simple, because it does not require chemicals and the use of magnetic roasting the ore pre-processing. Magnetic

Choice is the traditional craft of iron ore sorting. Nevertheless, when processing a joint process, iron hydroxides contained in the ore also adversely affect the flotation process,

Because when regrinding magnetic products, the formation of iron hydride part of the monomers.

    Magnetic separator magnetic separator operations are under the effect of the magnetic field, using its elemental iron material will be pulled out from the mineral mix. Then, in the use of magnetic separation

Machine, be sure to note is that the high gradient magnetic separator, magnetic separator machine operation requires a certain degree of systematization, will explain some common nouns

Will contribute to our understanding. Magnetic separation (also known as magnetic sorting) are separated based on different magnet neodym components of the magnetic material in the difference, using different types of magnetic separator

The various components of the material of magnetic separation technology.

    Magnetic force of the magnetic field of the peripheral space is called. The physical strength of the magnetic field is called the magnetic field strength. Process includes three sections closed-circuit crushing the ore crushed to

16 to 0 mm, milling and high intensity magnetic separation. Sorting according to stage 1 or 2 beneficiation processes. A beneficiation process is relatively simple, but easier option applies only to one thousand ore or

Used to select high quality concentrate. Krivoy Rog Mining oxidized quartzites that using this process. According to this process the crushed ore is first ground to a 0.074

Grain size 93 mm 95%. Three magnetic sorting and pre-screening of scrap iron.

    The first sorting the ore in the weak magnetic field will contain 1 to 10% magnetite ore sorting to orange. In the second sorting, according to the different content of magnetite, fine

Of 1.5 to 15% minerals. Weak magnetic intensity magnetic separation tailings to the entry, sub elect 58 to 62 percent of iron ore and iron 20 ~ 28% in the mine, the mine was concentrated in the same magnetic

Magnetic separator for re-election. The re-election of 10 to 15 percent recycled 54 to 58 percent of iron ore and 18 to 20% iron ore tailings total metal recoveries of 68 ~ 76%.

    Magnetic separator equipment maintenance operations: 1. Bearing shoulder the entire load of the machine, so good lubrication for the bearing life of a great relationship, it directly affects the

Life of the machine and the operation rate, which requires injection of lubricating oil must be clean, seal must be good, the machine main oiling Office (1) Turn the bearing (2) roller

Bearings (3) All gear (4) activities bearing, sliding plane. 2 newly installed tires prone to loosening must always be checked. 3 Note that the various parts of the machine work

Is normal. 4 note to check the wear parts wear, and pay attention to replacement of worn parts. 5 active device placed base of the plane should go out dust and other materials

In order to avoid the machine can not be broken material encountered activities bearings can not move on the bottom shelf, resulting in a serious accident. 6 bearing temperature rise, the reasons should be immediately stopped and checked

To eliminate them. 7 Turn the gear in operation should be immediately stopped if the impact of the sound check,

    According to various iron oxide magnetic quartzite and joint beneficiation process choose another result, Krivoy Rog Mining and Kursk magnetic anomaly ore ti: fine disseminated

And very fine disseminated iron oxide quartzite beneficiation process carried out research and experiments. Paragraph and the magnetic flux density at different Sec carried sorting. In the period, the main

To special sorting operation is 1.0, while the re-election of 1.5 special operations; in Sec mainly special sorting operation is 0.5, and the first and second re-election operations were 1.0 and 1.5

Special. Type magnetic separator used in sorting systems, mineral composition and metal minerals and non-metallic mineral beneficiation indicators dissemination size has a great influence on.

    Magnetic Separator full-time staff should be checked with the installation. (2) equipment installed on a level concrete foundation with anchor bolts. 3 should be installed Note

Means the vertical and horizontal main body. 4 Press the device power configuration the power cord and control switches. 5 Check completed, the empty load test, test the normal production
