secondary iron ore resources to get the desired quality. These resources mainly include low grade iron ores fines(−6 mm) and slimes (−150 μm). Indian iron ore typically comprises of good grade of iron along with relatively high amount of SiO 2 and Al 2 O 3 as the major tailor materials. Hematite iron ore in India is found in various forms ...

(v) It is not correct for the Revenue to take a position that as it is not possible by a physical analysis to determine the iron ore content in moist lumpy iron ore or moist iron ore fines, because moist iron ore fines and moist iron ore has to be dried for finding out the iron contents to be determined by the method of analysis extended by the ...
NOTE An equivalent International Standard that does not use mercury(II) chloride is ISO 9507:1990, Iron ores — Determination of total iron content — Titanium(III) chloride reduction methods. A suggested procedure for removal of mercury from the waste solutions before discharge to effluent drains is given in Annex C .
The use of magnetite-based iron ore fines by means of fluidized bed technology has become a promising route to produce direct reduced iron. The significant influence of a prior oxidation treatment, which occurs in the preheating stage, on the subsequent fluidization and reduction behavior was observed in our previous study. As a …
Fines iron ore oxides are generated during mechanized mining as well as comminution, beneficiation, transportation, and agglomeration processes. These iron ore fines need to be taken care of and reused in ironmaking. The present work focuses on the utilization of those fines by agglomeration techniques and converting them into reduced …
