Beneficiation of iron ore tailings is a significant issue in the world steel industries, from the point of view of both pollution control and secondary resources. This investigation addressed the processing of tailings with high sulphur content from an iron ore concentrator to produce pellet feed fines and to prevent acid mine drainage.
There is disclosed a process for scavenging iron from tailings produced by the flotation beneficiation of iron ore. This process includes the step of scavenging the flotation tailings using wet highintensity magnetic separation (WHIMS). There is also disclosed a process for increasing the recovery of iron ore in a flotation beneficiation process.
In iron ore beneficiation plants, ore is finely ground for liberation of the mineral. The fine tailings generated ore usually disposed in tailing ponds'. The tailing pond deposits can mostly be considered as permanent structures and always have impact on environment2.
Jan 04, 2007· Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include i. Dephosphorization. ii. Desulfurization. iii. Desiliconization. iv.

In over 90% of the global trade in iron ore, and increasingly with ore beneficiation and processing, most ore is of the banded iron formation (BIF) type. It consists of a mixture of hematite and magnetite with a finer component comprising the more weathered forms ferrihydrite and goethite. Goethite and ferrihydrite generally become entrained in water of most waterbased ore beneficiation plants (OBPs).

Processes for Beneficiation of Iron Ores Iron is an abundant element in the earth's crust averaging from 2 % to 3 % in sedimentary rocks to % in basalt and gabbro. Because iron is present in many areas, it is of relatively low value and thus a deposit must have a high percentage of metal to be considered ore grade.
