Effective Beneficiation of Low Grade Iron Ore . - Semantic Scholar

Vol.7, . Lot of developments in iron ore processing have been taken place in recent years in many iron ore producing countries of the world. The emphasis was on development of a cost effective flow sheet to beneficiate the low-grade iron ores to produce concentrates suitable for blast furnace, sinter or pellet making.


Oct 1, 2009 . This complex sequence is not cost effective for many low-grade ores that are resistant to physical concentration. For example, many ores contain iron oxide in a nonmagnetic form and are so fine-grained that it is uneconomical to grind them to a fine enough size to separate the iron oxides from the gangue.

characterization and processing of low-grade iron ore slime from the .

The beneficiation of iron ore slime produced from washing plants and tailing ponds of Kiriburu mines was studied (Prasad et al. 1988) using wet high-intensity magnetic separators (WHIMSs) followed by classification in hydrocyclone. They showed that a concentrate assaying 63% Fe and. 3.3% alumina could be produced.


content in concentrate 53.54%. By using magnetic concentration sample who have undergone the process of roasting at a temperature of 1000 oC have recovery results obtained at 88.5 % with Fe content in concentrate 60.52%, and 83.31 for Mn.

Maximizing the recovery of fine iron ore using magnetic separation

Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from -200 µm down to -10 µm. The general view is that this fraction is low grade in terms of iron ore.
