The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics. Further magnetic separation and milling produces even higher iron levels in the magnetite concentrate.

The obtained iron ore materials are moved to flotation desulfurization process, then to weak magnetic separation. The obtained product is iron ore concentrate. And low iron content material is discharged as tailings. You will also obtain sulphide concentrate as by-product through flotation desulfurization.

magnetic seperation of iron ore environmental impact. Iron Ore Magnetic Separation. Assuming that the amount of magnetic particles dropped by the separator is a nearly constant quantity, a higher percentage of recovery of iron is obtainable from a rich ore than from a leaner ore as the percentage of iron lost is evidently less.

Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

Dry Magnetic Separation of Iron Ore of the Bakchar Deposit. Fig. 5 shows the iron ore after the process of magnetic separation. The concentrate (b) has a pronounced dark color due to the iron oxides in its composition while the tailings (shown by clastic rocks) are lighter and partially transparent (a).

01-01-2015· The ore is mainly composed of magnetite, hematite, martite, and quartz. It is very difficult to produce a high-quality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% -75 μm.

Beneficiation of an iron ore fines by magnetization. Nov 10, 2017· These iron ores contain many detrimental impurities and are difficult to upgrade to make suitable concentrates for the blast furnace In this paper, the beneficiation of a low-grade hematite ore fines containing carbonates with magnetization roasting and magnetic separation was proposed and

Iron Concentrate By Magnetic Seperation. Weak magnetic separation weak magnetic separation is used to create cleaner ironrich products that can be reused these products have low levels of impurities and a high iron load this technique is used as a recycling technology it is coupled with steelmaking slag fines as well as a.

An implementation of two-step concentration (afterpurification) allowed increasing the iron content in the concentrate up to 48.2%. It forces to upgrade the process of dry magnetic separation or carry it out in the liquid phase (so-called, wet separation). Fig. 5 shows the iron ore after the process of magnetic separation.

Finally, an iron ore concentrate assaying a Fe grade of 62.12% with a recovery of 56.93% was prepared using wet magnetic separation at a magnetic intensity of 0.5 T from the ore roasted under the following roasting conditions: roasting temperature of 500 °C, reducing agent/sample ratio of …

Magnetic Separation, Magnetic Separation Process, Magnetic . Weak magnetic separationconcentration i characterized by the conventional magnetic separation of iron concentrate after the use of special equipment to further improve the grade of concentrate. Commonly used magnetic separation equipment including: magnetic separation column, magnetic

magnetite iron ore separation by magnet. Chili 120-150tph Station de concassage mobile de pierre de rivière. Chili 120-150tph Station de concassage mobile de pierre de rivière. Ligne de concassage de minerai de fer du Chili. Papouasie Nouvelle Guinée 250TPH Station de concassage mobile.

Various minerals in the feed sample, such as pyrrhotite, iron-rich sphalerite, and gangue minerals, were expected to show different responses to the magnetic-separation process. If iron-rich sphalerite was separated from other minerals, the effectiveness of pre-concentration would be manifested as a significant mass reduction for the next stage.
