The Run of Mine (R.O.M) sample assayed 21.91 % Fe, which is very low grade in nature.Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial Beneficiation of Iron Ores IspatGuru

Similarly, hematite (Fe 2O 3) content should be as low as 1% for refractory applications. The impurities in the bauxite affect its utilities and lead to an increase in production cost. Additionally, higher concentra-Conclusions. The investigations carried out on the low grade iron ore sample reveal the following conclusions. (1) The sample on average contains 43.8% Fe, 16.8% SiO 2 and 5.61% Al 2 O 3. (2) The mineralogical studies indicate that the major iron minerals are magnetite, hematite and goethite.

Chromite ore beneficiation: prospects and challenges
The beneficiation studies of Suresh (1981) illustrate that low-grade chromite ore of 16%–25% Cr 2 O 3 of Sitampundi area of India, cannot be upgraded by using conventional physical beneficiation techniques like gravity and flotation, due to the intimate association of iron in the lattice of chromite particle.These iron ores contain many detrimental impurities and are difficult to upgrade to make suitable concentrates for the blast furnace. In this paper, the beneficiation of a low-grade hematite ore fines containing carbonates with magnetization roasting and magnetic separation was proposed and studied.
