Jun 21, 2019· The concentrate consists of iron-rich oolite and some hematite, and has an iron grade of up to 55% [10–12]. Phosphorus in the ore is mainly present in the form of collophane, where the grain sizes of the collophane girdle and monomer quartz are relatively small, as are the monomer sizes of hematite and limonite. This results in di cult ...
Hematite - Wikipedia. Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe 2 O 3), one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on earth, and is widespread in rocks and soils [5] .
Jigging of iron ore fines was also taken up as the first choice in IMMT, Bhubaneswar to upgrade the iron content from the low-grade fines. The mineralogical characterization of Barbil area iron ore shows that it contains mainly hematite and goethite and minor amounts of kaolinite, gibbsite and quartz.
In addition to this, depletion of high grade iron ore, stringent environmental regulations involved in opening of new mines, problems involved in handling, disposal of tailings (slimes), and utilizing of iron ore at 45% Fe as a cut-off fixed by Indian Bureau of Mines, it is the need of hour to effectively beneficiate low grade iron ore.
