In the Indian context, BHQ iron ore typically consists of around 35–48 wt% of total iron content, i.e., Fe (T) alongside 40–45 wt% of SiO 2, and 0.5–2.5 wt% of Al 2 O 3 [4]. Due to the complex nature and low Fe content of BHQ, the separation of iron values from gangue impurities using conventional physical processes is very challenging ...

Natural ore, also known as "direct shipping ore," is ore that contains a high percentage of hematite or magnetite (more than 60% iron) and can be fed directly into blast furnaces to produce iron. Iron ore is a raw material used to produce pig iron, which is one of the primary raw materials used to produce steel—steel accounts for 98 per ...

India's iron ore mining industry is growing rapidly in order to augment the capacity to meet the unprecedented demand for the iron ore. Traditionally, much of Indian iron ore production came from ...

In this work, a compressive pelletization study was done for the utilization of an Indian BHQ ore sample. Iron ore concentrates have been generated via two routes, such as the conventional magnetic separation and the coupled approach of reduction roasting and magnetic separation. Synthesized magnetite pellet produced from the iron ore ...

Due to the depletion of high-grade iron ores and their simultaneous demand, the utilization of low-grade iron ores such as banded hematite quartzite (BHQ) has become a topic of research interest around the globe, particularly in India. These low-grade iron ores are reckoned to be the future feedstock for iron and steel making industries.

According to National mineral policy projections, exploitation of the low grade iron ore horizons like BHJ, BHQ, and BIF etc. is necessary to achieve zero waste mining. BHJ assaying up to 40% Fe(T) has to be upgraded above 60% Fe(T) to use effectively It may also be noted that attaining liberation may be an extremely difficult job requiring ...
