Advances in Low Grade Iron Ore Beneficiation

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

Beneficiation Study of Barsuan Iron Ore Slime to Produce ...

The slime sample collected from Barsuan assaying 54% Fe, 8.3% SiO 2 and 11.08% Al 2 O 3 analysed for pre-concentration of iron values using hydrocylone for desliming followed by magnetic separation. The results confirmed that Magnetic separation is a better pre-concentration technique as compared to hydrocyclone.

Beneficiation of Fine Iron Ores using the Desand Process

The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine (<0.010 mm) clay-rich slimes simply …

Magnetic carrier technology has been established in the commercial-scale for wastewater treatment but needs to be translated in iron ore beneficiation by incorporating natural or colloidal magnetite. Similarly, bio-beneficiation processes with gangue reducing bacteria have to be studied at a much larger scale before they see the light of the day.
