Iron Ore ScienceDirect
Abstract. Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world’s largest trillion-dollar-a-year metal market and is the backbone of global infrastructure. To meet the growing demand for steel products, world iron ore production has increasedGravity and magnetic separation methods are basic ore processing techniques for obtaining the iron con-centrates [4]. Wet low and high intensity magnetic se paration methods are appropriate methods to process these ores with high iron content and a high degree .

Mineral and Technological Features of Magnetite–Hematite Ores
Analysis of the current technical solutions for the processing of iron ores showed that the high-grade ores are directly exposed to metallurgical processing; by comparison, low-grade ores, depending on the mineralogical and material composition, are directed to beneficiation including gravitational, magnetic, and flotation processes or Intensity Magnetic Separators) commonly use an alloy of neodymium, iron, and boron (NdFeB). Magnetic separation process Magnetic separation technology can roughly be divided into three classes of magnetic intensity i.e., low, medium, and high, all depending on the characteristics of the minerals subjected to magnetic processing:For dry and wet processing Low Intensity Magnetic Separators

Existing and New Processes for Beneficiation of Indian Iron ores
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional ore processing techniques for obtaining the iron con-centrates [4].
