In the past, this low-grade iron ore was crushed and classified into coarse and fine fractions, with the coarse fraction reductively roasted and the fine fraction processed in a gravity-high-intensity magnetic separation-flotation flowsheet. This flowsheet produces a relatively low-grade concentrate assaying around 63% Fe at a low recovery. In the past decade, with development of SLon

Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in consumer demands. Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores.

Low-grade ore is a term applied to iron-rich rocks with cut-off grades in the range of 25�30% Fe. It was the main supply of iron ore for many centuries of the World''s early history of production of iron. Since the 1950s North America''s main supply has been low-grade ore. The dominant economic iron mineral in low-grade ore is magnetite

Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. The beneficiation process should be as efficient and simple as possible, such as the development of energy-saving equipment, and the best possible

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 bearable utilization of iron ore can be achieved. 3 Fig 1.1
