— Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO 2, and 4.5% Al 2 O 3.

 — This comprehensive review explores various beneficiation techniques for low-quality iron ore, focusing on conventional methods including comminution, froth flotation and gravity separation. This article discusses the principles, processes, and equipment used in these techniques and highlights recent advancements and research efforts in the field.

The STET tribo-electrostatic technology has been used to process and commercially separate a wide range of industrial minerals and other dry granular powders. Here, bench-scale results are presented on the beneficiation of low-grade Fe ore fines using STET belt separation process.

addition in existing iron ore production by 2020, there is an urgent need for conservation and sustainable use of our natural resources. More than that, there is also a need for effective utilization of low-grade iron ore and fines, …

 — The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand globally necessitate efficient low-quality iron ore beneficiation to meet steelmaking quality requirements.

 — In the low-grade iron ore deposits (45%–55% Fe), there is a complex association of gangue mineral with Fe-bearing minerals, which makes it challenging to beneficiate the iron ore concentrate as per downstream requirement.

 — With increasing global demand of iron ores due to the huge requirement of steel all over the world, important iron ore producing countries have increased their production by initiating steps to utilize the low-grade iron ores, fines and slimes.

 — Upgrading low grade iron ore fines using a combination of microwave roasting with waste off-gas from ironmaking, therefore, offers significant advantages to iron ore producers and iron makers in reducing overall CO 2 emissions.

 — The current beneficiation study examines the potential for separating ultrafine low-grade iron ore materials using a circulating-type air classifier.

 — In the present study a detailed characterization followed by beneficiation of low grade iron ore was studied. The Run of Mine (R.O.M) sample assayed 21.91 % Fe, which is very low grade in...
