In the process developed by Das and coworkers (2000), the tailings are mixed with clay and a fluxing material (40-50 % tailing, 30-50 5 clay and 10-15 % fluxing material). The raw materials are wet milled for 10 h to obtain the desired fineness. The slurry obtained is screened, dried at 110 °C, powdered to break the agglomerate and granulated ...

Another factor has received less attention. DRI steelmaking requires a higher grade of iron ore than blast furnaces, the dominant global process. DR-grade iron ore ideally has an iron (Fe) content of 67% or more and such deposits are scarce --only a small percentage of global seaborne iron ore comes close to DR-grade.

Grab-sampling by an interested party, at its best, is only a prejudiced conjecture, while at its worst it gives rise to the most unscrupulous practices with which the ore-producer and the mining-investor have to deal. Shovel-sampling, another archaic method which is still used in some localities, consists in throwing out from the car or …

What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its abundance. …

Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation. The present study aims to recover iron values from discarded slime containing assay ~56% Fe, ~6.5% SiO2, and ~7.0% Al2O3 from Noamundi processing plant by using high gradient magnetic separator (HGMS).
