Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.

Oolitic iron ores are a distinctive subset of iron ore deposits, and are characterised by their spherical grains composed of concentric layers containing hematite and goethite along with impurity elements such as silicon and phosphorus. Depending on their petrology, oolitic iron ores may require very simple or extremely complex

Hematite, also known as red ore, whose chemical formula is ferric oxide (Fe2O3), is a weakly magnetic iron mineral with better floatability than magnetite, and is one of the main raw materials for iron making. Its crystals are oxide minerals of hexagonal crystal system, and the mineral form is mainly iron oxide.

The current centrifugal concentrators do not continuously concentrate heavy minerals of large mass weight—for example, in the processing of iron oxides. A cyclone centrifugal separator is a new type of beneficiation equipment that has been developed on the basis of the principles of centrifugal separation and hydrocyclones. In this study, a

DRI relies on the fact that it does not require cokemaking and sintering and there are almost no gas emissions during the reduction process [2, 3]. Fine iron ore accounts for about two-third of global iron ore production . The advantage of DRI process is that fine iron ore can be used directly without prior treatment.

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,

Hematite Processing by Flotation Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves.

Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red;

In some places reduction roasting of the low grade hematite ore is done to convert it into magnetic ore before the application of the magnetic separation method for the ore beneficiation. Another method which can be employed is the use of a dense medium in a gas-solid fluidized bed for the enrichment of iron ore.

The reduction of iron oxide occurs in three general steps, namely hematite to magnetite, magnetite to wustite, and wustite to iron [ 18 ]. Coal plays a dual role in the process by acting as a reductant as well as a fuel for providing heat to maintain the required temperature (900–1050 °C) [ 19 ].
