Iron ore is the basic raw material for iron and steel making. India is among the leading producers of iron ore in the world and produces about 150 million tons per annum (U. S. []).The total reserves of iron ore in India is around 28.5 billion tons, of this hematite ore is considered to be the most important iron ore because of its high grade The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay Beneficiation of Clay-Rich High-LOI Low-Grade Iron Ore

The effect of mineralogy and texture on the beneficiation of goethitic ores from two different origins is highlighted. Sample A having 54.47% Fe with 8.57% loss of ignition (LOI) indicates the presence of vitreous and ochreous,martite and microplaty hematite + 100 μm size class are 74% for Sample A and 37% only for Sample B which The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and Iron ore beneficiation: an overview ScienceDirect

The table concentrator, which is a traditional beneficiation equipment, was used by Roy et al. to separate low-grade iron ores with high hematite and goethite contents (Roy and Das, 2009). The properties of ores were found to play an important role in the separation process.Banded Iron Formations (BIF) are sedimentary rock formations ranging in age from 0.8 to 3.8 billion years and consist of alternating layers of silica and iron.

The application of bio-organisms such as Bacillus subtilis, Saccharomyces cerevisiae and Desulfovibrio desulfuricans in the beneficiation of hematite ores has been reported [54, 55]. Several other microorganisms including autotrophic and heterotrophic bacteria, fungi, yeast and algae can also be applied in iron ore beneficiation.To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3.

Beneficiation of alumina rich iron ore slimes is a major challenge for the Indian iron ore industry. High alumina is deleterious for the performance of both blast furnace as well as sintering plants.2 天之前The optimum grade that could be obtained from single-stage dry magnetic separation was 35.52% Mn, and with a Mn:Fe ratio of 1.77, and 44% Mn recovery in the case of sample 1; whereas, a 33.75% Mn grade, with a Mn:Fe ratio of 1.66 at Mn recovery of 44% was reported for Sample 2.
