Abstract. Iron ore is ferrous group of mineral and is the backbone of industrial development and its demand has drastically increased with the increase of industrial development. Since, the high grade iron oxides are depleting very fast and to cope up with the increased demand of the industry, the low grade iron ore in general has become the eye catching of iron industry and
range. The residual are low grade, unclassified resources of lumps and fines or high, medium, low or unclassified grades of lumps and fines mixed. The cut-off grade for estimating the hematite resources has been taken as 57% Fe. If the cut-off grade is reduced to say 43% Fe, the iron ore resources will increase considerably and thus
important that we should plan to use low grade BHQ BHJ iron ores after beneficiation. Looking at the present scenario IBM has slashed the threshold value of 45% Fe(T). According to National mineral policy projections, exploitation of the low grade iron ore horizons like BHJ, BHQ, and BIF etc. is necessary to achieve zero waste mining.
These results indicated that the BHQ ore can be beneficiated to generate iron fines with 66% Fe with low silica content. An iron concentrate containing 63.1% Fe can be achieved by the combination of low and high wetting magnetic separation. The concentrate thus produced is superior in quality
Apr 11, 2019 The depletion of high grade iron ore resources make it inevitable to utilize the existing low grade iron ores/fines/tailings with effective beneficiation to meet the present specification and demand. Enormous amounts of fines are produced both from the natural geological process as well during the mechanized mining operations which is hitherto in
The efficiency of iron recovery is 90-95% (as against 70-75% in the conventional beneficiation plants) the left-over Fe in the tailings is only 10-15% (as against 35-45% in the conventional beneficiation plants). In the process, low grade iron ores are dry-ground, preferably to their liberation size passed through a fluidized bed roaster.
