Understanding the high-grade iron ore market
iron ore worldwide at lower in-situ grades (generally about 20-40% Fe), which can be readily enriched during beneficiation processes - using gravity or magnetic separation - to increase their purity to upward of 65% Fe. In an economically viable operation, the cost of processing the ore can usually be offset by the price premium the high-purity ...
