Iron Ore Department for Energy and Mining

The world's resources are dominated by low-grade ore, though current world production of iron ore is largely by supply from deposits of high-grade ore composed of either rocks of massive hematite or pisolitic goethite. World iron ore production in 2013 was 2.95 billion tonne, with the major producers being China, Australia, and Brazil.

The high-grade iron ore premium has peaked CRU

Oct 31, 2018 Another advantage of using high-grade iron ore is that it reduces coking coal consumption during hot metal production. This means steelmakers can use high-grade iron ore as a way of reducing coking coal costs, which becomes particularly important in a high coking coal price environment. We note that China only imports 7% of its coking coal needs.
