1) Gravity separation The true specific gravity of iron ore is approximately 5t/m3 and is quite different from the specific gravities of major impurities such as silica and alumina (approximately 2.7t/m3). Gravity separation is a method of separating iron ore from impurities on the basis of the difference in their specific gravities.

Gravity separation. Gravity separation has been used for REM beneficiation extensively in the context of heavy mineral sands processes, where separators such as spirals and shaking tables are used as gravity preconcentration steps (Gupta and Krishnamurthy, 2005, Moustafa and Abdelfattah, 2010). These gravity separations are successful due to ...

growth of the iron ore industry some. Major reason for difficulty in beneficiation of BHJ is revealed from characterization studies which show the intergrowth of haematite and quartz. Presence of Kaolonite is proved with the aid of mineralogical studies. For the separation of alumina from iron ore Beneficiation studies have to be carried out.

· Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore. It responds best to what is known as gravity separation as well and several types of gravity equipment can be used to refine it, including jiggers, centrifugal separators, and shaking tables.
