dry magnetic separation iron ore

Magnetic separator separates theiron 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.

Jan 01, 2015· Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a highmagnetic susceptibility(as a rule, 20– 90·10-7 m3/kg8).

Thedry magnetic separationresults were judged as acceptable for the rough processing stage, while the products of the wetmagnetic separationwere the high-gradeiron oreconcentrates. The two ...

As one kind ofmagnetic separationequipment,Magnetic Ore Separatorare designed for sorting and pre-separationof low gradeironores, raisingoregrade and reducing production cost. They are suitable for using in arid regions that short of electric power because they did not need water resource and even can be driven by diesel engine.

Dryprocessing ofiron orepresents an opportunity to eliminate costs and wet tailings generation associated with flotation and wetmagnetic separationcircuits. STET has evaluated severaliron oretailings and run of mineoresamples at bench scale (pre-feasibility scale).

Thedry separatoris used foriron orewith particles sizes up to 20 mm. Themagneticsystem is available in five designs and allows for very highest loading with excellent selectivity at highest recovery, which reduces the number of units required. Fewer machines means less …

The alternative isdry magnetic separation, but many laboratory tests have shown that it is not as efficient as wetmagnetic separationin the fine particle ranges. However, someiron oreresources are located indryareas where adequate water supply is very difficult to obtain and hencedry…

Probably the biggest financial failure of Edison's career was themagnetic ore-separator. The idea, which Edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separateiron orefrom unusable lower-grade ores. This would mean that abandoned mines could be profitable once again through the extraction ofiron...

The rare earthmagnetic separatorrange achieves the most effectivedry separationof paramagnetic minerals at high throughput rates. The range includes Rare Earth Roll (RERS) and Rare Earth Drum (REDS) Separators which are available in a range of configurations …

Apr 03, 2014·Magnetic separation.Magnetic separationtechnologies are used to take the advantage of the difference in themagneticproperties for separatingiron orefrom the nonmagneticassociated gangue materials.Magnetic separationcan be conducted in either adryor wet environment, although wet systems are more common.

Beneficiation ofIron Oreand the treatment ofmagnetic irontaconites, stage grinding and wetmagnetic separationis standard practice.This also applies toironores of the non-magnetictype which after a reducing roast are amenable tomagnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500 ...
