The magnetic separator is suitable for magnetite and magnetic yellow iron with a particle size of 3 mm or less. Wet magnetic separation of minerals, roasted ore, ilmenite, etc., is also used in iron removal operations for coal, non metallic minerals, building materials and other materials.
A continuous flow magnetic particle separator and accompanying classification method is disclosed for ferromagnetic and paramagnetic particles. A magnetic field is generated, preferably by a coil or solenoid mounted interiorly of a cylindrically configured ferromagnetic conductor. The classification volume is located in a typically toroidal volume interior of the magnetic field.
Iron ore magnetic separator is the mainly used iron beneficiation technic due to the magnetic properties of iron ore as a world leading supplier and manufacturer.
Production practice of iron ore tailings re election indicates that ore concentrator factories discharge 2.28 million tons of tailings a year. The tailings processed by the JHC rectangle ring type magnetic separator, and we gained elected rough ore concentrate, and then the concentrator is pumped to a separate built concentrate plant.
The iron recovery increased by 6.68 compared with the conventional magnetic separation. The high efficiency in beneficiation may be attributed to an increase in magnetic force on the micro fine.
Conclusions Iron content in obtained product (non magnetic fraction) after magnetic separation on black tailings with weak magnetic field is 24.75 which approximately equals iron content (24.02 ) after high intensity magnetic separation of the raw tailings obtained in Kremikovtzi Mineral Processing Plant by new technology.
Xinhai Magnetic Separation Discarding Tailings Process Xinhai magnetic separator is widely applied in the wet magnetic separation process of magnetite, pyrrhotite, roasted ore and ilmenite (below 3 mm), also used in iron removal of coal, non metallic mineral and building materials.
Content up to 91.03 while reducing the iron content to 0.32 by using magnetic separation. After the calcination process at 1000 oC, the sample showed mass loss on ignition of 52 and contained 85.39 MgO with 0.32 Fe 2 O 3. The final product can be used in chemical and metallurgical applications where high magnesia contents are required.

Today, magnetic separation techniques are used to beneficiate over 90 percent of all domestic iron ore. Between 20 and 35 percent of all the iron units being beneficiated in the United States today are lost to tailings because hematite is only weakly magnetic.
Which is suitable for pellet making from iron ore tailings of G ncem Mining Company magnetic separation facility. During the study, tailings named as low grade and medium grade with 5.91 Fe.
In this process, the tailings is effectively roughed with pulsating high pulsating high gradient magnetic separator to produce a relatively high grade iron concentrate, then this concentrate is cleaned with a continuous centrifugal concentrator to produce a high grade iron concentrate.
Jan 01, 2019 The Fe grade of the tailings sample (Table 1) is 30.3 wt and can be used as feed in industrial beneficiation plants that use iron ore with Fe grade between 25 wt and 45 wt . In addition, the tailings sample between 0.297 mm and 1.4 mm has SiO 2 greater than 65 wt and approximately 20 wt Fe. Table 1. Chemical analysis by fraction.
In this study, a process of magnetizing roasting followed by magnetic separation, which is used to separate or recover tin and iron from the high calcium type tin and iron bearing tailings (containing 35.53 wt. Fe and 0.56 wt. Sn), was investigated .
The maximum recovery of Fe reached 77.8 at 600 C, and the grade of total Fe in the magnetic concentrate was 56.3 wt. . An innovative approach, using water to leach REEs after (NH4)2SO4 activation roasting, was used to extract REEs from magnetic separation tailings.
The low price iron tailings are used as the raw materials of cement production and applied to concrete, which will bring great economic benefits. Li made cementing materials from iron tailings, blast furnace slag, cement clinker and gypsum with a ratio of 30 34 30 6, whose strength can reach the standard of 42.5 grade silicate cement.
Under these conditions, the magnetic concentrate containing 68.5 Fe and 0.06 Sn was achieved, which can be used as high quality raw materials for direct reduction iron production. Keywords Iron tin bearing tailings Magnetizing roasting Magnetic separation.
And the ignition loss of concentrates and tailings obtained are above 55 and below 5 , respectively, which can be for further use. Based on the relatively high contents of iron in flotation tailings, magnetic separation for iron enrichment was carried on subsequently. After concentration, the content of Fe 2 O 3 in iron concentrate is above 60 .
Chemical analysis showed the tailings comprised 26.2 Fe, 18.6 Si, 3.9 Al, and 1.07 total rare earth oxides (TREO). A rougher–scavenger–cleaner magnetic separation process was deployed to produce two useful streams of REE minerals concentrate and tails using a wet high intensity magnetic separator (WHIMS).
Typical metallurgical results indicated the rejection of 25 of the iron oxides at 0.11 T, whilst producing a magnetic concentrate with TREO recovery of 51 at a grade of 1.25 and non magnetic tails with TREO recovery of 41 at a grade of 1.08 , both at 1.74 T. Bastn site, monazite, florencite, and stillwellite minerals were confirmed to be paramagnetic, whilst stetindite and brannerite were found to.
Xinhai tailings re processing line, with the thought of protecting ecosystem and fully using resources, provide a re processing for tailings of iron, gold, Lead zinc, copper, fluorite, and so on. Xinhai can design reasonable.
An iron concentrate containing 66.35 Fe with a total recovery of 57.74 was produced underEvaluation of Additional Iron Recovery from Iron Ore .Wet magnetic separation of Abagur tailings 0.007 mm in size allowed recovery of 0.6 to 1.45 of magnetic fraction with Fe total content of 53.3 and 51.6 , .(PDF) HIGH INTENSITY MAGNETIC SEPARATION OF.
Abstract. High calcium type tin , iron bearing tailing is recognized as one of typically complex iron ore resources in China. A process of magnetizing roasting process followed by magnetic separation was used to utilize the tailings in our previous paper.
