According to Fastmarkets’ estimates shown in figure 2, around 37% of total exports can be considered ‘high-grade’ (>63.5% Fe), around 44% ‘mid-grade’ (59-63.5% Fe), and a remaining 19% ‘low-grade’ (<59% Fe). Fines account for by far the largest volume of export trade, followed by lump and then pellet and pellet feed.

· Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its abundance.
