Iron ore beneficiation plant
Iron ore beneficiation plant is used to beneficiate
a wide variety of industrial iron ores. In this application the relatively large volumes of
nonmagnetics are usually the commercial products. The amount of magnetic material removed is
quite small, and dry separation is the general rule. Iron ore processing plant is also important
in processing phosphate, titanium, chrome, manganese, tungsten, molybdenum, nickel, niobium and
tantalum ores.Magnetic separation of iron ores is one of the fastest-growing segments of the
minerals beneficiation industry. The tonnage of taconite ores processed annually by magnetic
separation zcill, in a few years, reaches 100 million.Magnetic separation occupies an attractive
position in the field of ore beneficiation. This type of beneficiation originated in 1792, when
William Fullarton was issued a British patent covering the separation of iron ore by magnetic
attraction.

Iron ore beneficiation preparation
Very low grade Iron ore cannot be used in metallurgical
plants and needs to be upgraded to increase the iron content and reduce the gangue content. A process
adopting to upgrade ore is called Beneficiation. Iron ore is upgraded to a higher iron content through
concentration. Iron ore is being beneficiated all round the world to meet the quality requirement of
Iron and Steel industries. However, each source of Iron ore has its own peculiar mineralogical
characteristics and requires the specific beneficiation and metallurgical treatment to get the best
product out of it. The choice of the beneficiation treatment depends on the nature of the gangue present
and its association with the ore structure. Several techniques such as washing, jigging, magnetic separation,
advanced gravity separation and flotation are being used to enhance the quality of the Iron ore.Due to the
high density of hematite relative to silicates, Ore separating line usually involves a combination of
crushing and milling as well as heavy liquid separation. This is achieved by passing the finely crushed
ore over a bath of solution containing bentonite or other agent which increases the density of the solution.
When the density of the solution is properly calibrated, the hematite will sink and the silicate mineral
fragments will float and can be removed.

Iron ore concentrator from Shanghai Zenith The Iron Ore Beneficiation
has taken an important position in aligning plant strategies. Leading professionals from the industry have
decided to put in efforts to spot ways to make the process more efficient, aiming at zero waste management
for sustainable development which is synonymous with the concern for environment along with its social and
economic goals.Today, with metal companies being freely permitted to import rich ores at low tariffs, mining
these lean ores makes bigger challenge to have an economic sense, in order to effectively utilize
conserve the resource.
