Development of process for beneficiation of low-grade iron ore
Indian iron ores are rich in iron (Fe) content, with 62 to 64 percent Fe, and contain 2.5 to 3 percent alumina. The major iron-bearing minerals are briefly described in Table 1. Due to the high alumina content, the Indian iron ore beneficiation process has not yet found much importance compared with those in the rest of the world.Beneficiation of 22 mm low-grade iron ore tailings (507%Fe, 108%SiO2 and 44%Al2O3) from Western Australia was studied.

Recovery of Valuables From Low-Grade Iron Ore Slime and
Physical processing of low-grade (28% Fe) iron ore slime from Krivoy Rog province of the Ukraine is investigated. The slime is shown to have drastically different characteristics from those of Indian iron ore slimes. Effective recovery of iron values through physical beneficiation of the Ukraine slime is achieved.

Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.During mining, beneficiation and transportation of these manganese-bearing ores up to 30% of the ore produced is converted into −10 mm low grade Mn ore fines.
