Managing Iron Ore Fines of Dalli – Rajhara For Improvement In YieldAdoption of a combination of techniques for mining, beneficiation, sintering and pelletisation of ore has resulted in increased use of the fines in iron making. Low-grade ores, with iron content lower than 58% are now used, resulting in increase in mine life and reduction of waste, thereby reducing the need for additional land.iron ore beneficiation yield,Reprocessing of iron ore beneficiation plant tails - irjetintensity magnetic concentration yielding pellet grade concentrates, while the WHIMS-spiral tails and untreated slimes constitute the final tails dumped in the tailing pond. The tails were collected from tailing ponds of the beneficiation plant to study the amenability of the sample to produce cement grade iron ore concentrates.

Iron ore - Wikipedia

The typical grade of iron at which a magnetite-bearing banded iron formation becomes economic is roughly 25% iron, which can generally yield a 33% to 40% recovery of magnetite by weight, to produce a concentrate grading in excess of 64% iron by weight. The typical magnetite iron-ore concentrate has less than 0.1%.
