Oman has experienced steady expansion of their iron ore beneficiation and steel production capacities from 2007 to 2015, with a number of additional works either currently under construction or in the planning phase.
— Low-quality iron ore beneficiation is an essential process in the utilization of iron ore deposits, particularly as demand for iron and its alloys continues to rise due to rapid industrialization and depletion of high-grade reserves [4,5].
and ranks fourth with respect to world iron ore production. The existing reserves of hematite (averaging around 63 % Fe) are the only source of iron ore and as such, these reserves may not last beyond 25–30 years at the present rate of consumption. ... Low Grade Iron Ore Beneficiation In the past 50 years, due to high demand and intensive ...
