Banded iron formations of the Iron Ore Group (Archean greenstone belts) of Jharkhand-Orissa region, India host a good number of large iron ore deposits (Fe wt %> 62). Iron ore mineralization of Gandhamardan hill is one of them where iron ores occur in two stratigraphic horizons. One is strictly confined within banded iron formation (stratabound mineralization) …
The major types of iron ore formations in India are banded iron formations from the Precambrian era and laterite ores derived from sub-aerial weathering. The key iron ore minerals are magnetite, hematite, siderite and limonite. India's major iron ore mining districts are located in Odisha, Jharkhand, Chhattisgarh, Karnataka, Goa and other states.
Due to the rapid depletion of high-grade iron ores and exponential demand for steel, it has put pressure on iron resources of India in respect of grade and reserve. To overcome the demand, low-grade iron ore resources like Banded Hematite Quartzite (BHQ) and Banded Hematite Jasper (BHJ) need to be utilized for a sustainable future.
The high-grade (>62wt% Fe) iron ores of Kiriburu-Meghahatuburu deposit (KMID) of the Singhbhum-Orissa region, eastern India are mainly hosted by banded hematite Jasper (BHJ) and shale.

Banded iron formation or BIF is a chemical sediment, typically thin-bedded or laminated with > 15% iron of sedimentary origin (Figure 8.6).BIF has a very distinct distribution with time (Figure 8.25).It is found in minor amounts in …
The metamorphosed Banded Iron Formation (BIF) of Gorumahisani-Sulaipat-Badampahar (GSB) belt in Precambrian Iron Ore Group, Singhbhum Craton, is well known in the mineral map of India. Detailed characteristics of iron ore and iron-containing rocks in BIF have been investigated at different mine profiles and results are interpreted in terms of their genetic evolution. The BIF …
The majority of the iron ores in India are also associated with hydroxyl-bearing minerals such as goethite and limonite. The goethite content varies from 10–50% in low-grade hematite iron ores. ... found that the microwave pre-treatment followed by milling of hard and banded iron ores reduced the 80% passing size of the ground product by 20.83%.

Banded Iron Formations (BIFs), as the name suggests, are chemically precipitated sedimentary rocks having alternating Fe-rich and Si-rich bands. The origin of BIF has always remained a debated topic of research. The BIF in the Badampahar Greenstone Belt is of Mesoarchean age that formed a part of the East Indian Shield. Here, the BIF is interlayered with metavolcanic …
