The banded iron formation of Banded Hematite Jasper is a very low grade iron ore that usually contains Fe in the range of 30-40% depending on the origin. Banded hematite Jasper obtained from Barbil region of India and assaying 41.9% Fe, 38.4% SiO 2 and 0.4% Al 2 O 3 was studied for pre-concentration of iron values adopting Jigging and Dry High Intensity Magnetic Separation.

iron ore separator machine banded iron formation goa india Iron ore - Wikipedia The Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
Numerous iron ore deposits are hosted within the Meso to Neo-Archean banded iron formations (BIFs) extending across the Singhbhum-Orissa Craton, eastern India. Despite the widespread distribution of BIFs, which forms part of the iron ore group (IOG), heterogeneity in their grade and mineral composition is occasionally observed even within a single ore deposit.

On the basis of mode of occurrence and origin, the iron ore deposits of India are divided into five groups; viz. Banded Iron Ore Formation, Sedimentary iron ore deposits of sideritic and limonitic composition, Lateritic ores derived from sub-aerial alteration of gneiss, schists etc., Titaniferous and Vanadiferous magnetite deposits and Fault ...
The Precambrian banded iron-formations and the manganese ores of the Singhbhum region of eastern India occur within a sequence of predominantly volcanogenic metasediments (Iron Ore Supergroup) which occur around a central granitic platform.
Banded iron formation (BIF) is the principal source of iron. BIF is a rock type composed of alternating silica- and iron-rich bands. Banded iron formation is economically among the most important rock types as our society is heavily reliant on iron, which is mostly extracted from this rock.
Banded iron formations may contain iron in carbonates (siderite or ankerite) or silicates (minnesotaite, greenalite, or grunerite), but in those mined as iron ores, oxides (magnetite or hematite) are the principal iron …

Iron is a primary raw material for steel industry. Increase in demand for steel puts pressure on iron resources of India in respect of its grade and reserve. With increase in demand for good grade of ore vis-a-vis its limited reserve, the utilization of low to medium grade iron ores is the order of the day with adoption of advanced beneficiation techniques.
