Iron ores come in come in many shapes and sizes (and mineralogies), so there is no one size fits all approach to beneficiation. For magnetite ores, it is typically necessary to liberate the individual magnetite grains from the host rocks, after which beneficiation is relatively straightforward due to the magnetic properties of magnetite.

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
The iron itself is usually found in the form of magnetite (Fe3O4), hematite (Fe2O3), goethite (FeO(OH)), limonite (FeO(OH).n(H2O)) or siderite (FeCO3). Major components: Fe3O4, Fe2O3, FeO(OH), FeCO3, etc. Mohs hardness: 5.0-6.5 Available machines: Jaw Crusher, Ball Mill,Magnetic Separator Applications: Metallurgy, Beneficiation Iron Ore Crushing:
Size classification will require screening, de-sliming and cycloning. In the case of a lower-grade iron ore, the beneficiation process includes activities such as crushing, milling, gravity or heavy media separation, screening and silica froth flotation. These activities will help improve the concentration of the ore and remove impurities.
Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation. At the first stage, extracted ores undergo the milling operation to produce uniformly sized particles for crushing, grinding, wet or dry concentration.
The processes selected to reduce impurity levels of these lower-grade iron ores will depend on the ore mineralogy and a thorough understanding of the separation process dynamics. The major concentration methods that may be applied to upgrade lower-grade lump iron ores include magnetic separation, wet and dry heavy media separation, and air ...

Based on characterization results, two process flow sheets comprising wet screening followed by conventional gravity concentration and two stage classification with different beneficiation routes were used to recover the iron values from reject fines containing 58.73% Fe, 5.54% Al 2 O 3, and 6.6% SiO 2.
A similar processing flow sheet was described by Zhao (2008) for processing oolitic hematite ore associated with the Longyan Iron Mine of Xuan Steel in Hebei province in China. The ore contained 47.66% total Fe and was ground to 65% passing 74 µm ahead of gravity separation.
Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation.
These techniques are used in various combination s for the benefaction of iron ores. For benefaction of a particular iron ore the emphasis is usually to develop a cost effective flow she et incorporating necessary crushing, grinding, screening and benefiting techniques which are necessary for the upgrading of the iron or e.
