energy efficient large iron ore magnetic separator

From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pigironis the mostenergyintensive process for steel production at roughly 13.5 × 10 9 joules per ton (1000 Kg) of pigironproduced. The basic oxygen furnace is the second mostenergyintensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc furnace has significantly lessenergy...

Upper attractingmagnetic separator. Applicable Scope：The machine is a new type ofenergy efficient magnetic separatorapplicable to different specifications of conveyor belt.It is mainly used foriron separationfrom various kinds of metallurgical slag including scrap steel, steel slag, direct reductionironplant and casting workshop etc.

Energy efficient magnetic separator. Due to the recent state’s high attention to the rational application of environmental protection andenergy, it will promote theefficientuse ofmagnetic separatorequipment. Saveenergy, consume a small amount of electricalenergyduring the operation of the device, no need to consume current.

Feb 24, 2015· A significant fraction ofiron oreused in steel production comes from magnetite deposits. Magnetiteiron orerequires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot ofenergy. This article investigates eco-efficientalternatives for the process design for magnetiteiron ore.

The Vertimill is always moreefficientthan a ball mill withenergysavings ranging from 30% to greater than 50%. The transition point from the Vertimill to an SMD varies depending on theoreproperties but generally is in the range of 20 to 40 microns. A detailed test program can be carried out to determine the optimumenergy efficientcircuit....

How can theenergy efficiencyof HPGR be enhanced? This paper reviews recent HPGR applications for the processing particularly of copper, gold, platinum, PGM-Ni-Cu andironores. HPGR technology is discussed with respect toenergy efficiency. The harder theorethe greater theenergysavings are likely to be. Typicalenergysavings of 10-20% ...

Oct 04, 2018·Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings.

ROMoreis crushed and ground to 63µm. Groundoreis then fed to a wet high-gradientmagnetic separatorto produce amagneticconcentrate rich in xenotime andironoxide. Concentrate then passes through the float circuit to produce total rare earth oxide concentrate, which is thickened and filtered prior to being fed into the ...

Investigations carried out on a wet high-intensity magnetic separator using a low-grade iron ore sample containing 49.27% Fe shows that it is possible to upgrade to …

Dry high intensitymagnetic separation(DHIMS) is investigated to process a lean hematiteore. It was found the feed particle size and the drum rotation speed have significant influences on the ...

The allgauss®magnetic separatoris used mainly for separating the finest grains based on theirmagneticproperties, as in finely intergrown ores. The machine separates paramagnetic and lowmagneticminerals of up to 3mm grain size in a wetseparationprocess usingmagneticfields.

Magneticseparation is the only effective way of separating thevaluable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility (as a rule, 20– 90·10-7 m3/kg8).
