In recent years, the rapid development of China's iron and steel industry has led to a rapid increase in demand for iron concentrates. On the one hand, the decreasing iron-rich ore is not enough to satisfy the demand of the iron and steel industry; on the other hand, it further leads to a large number of iron ire tailings [1, 2].Iron ore tailings …

Iron ore is at a transition point. The same drivers of rising prices through 2019/20 went into reverse from mid-2021: supply constraints started to ease, but more significantly, the long awaited and much talked about cuts to Chinese steel production started to take effect, reinforcing our view that 2020/21 = peak hot metal production for …

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.

Lu et al. studied the effect of sodium sulfate addition on the hydrogen reduction of nickel laterite ore. A low-grade Indonesian nickel laterite ore containing 1.38% Ni, 25.3% Fe, 15.0% MgO, and 19.1% SiO 2 was used in the experiments. Reagent-grade sodium sulfate was used as an additive, and H 2 reduction was conducted. In each run, …

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.
