Iron oxides (hematite (Fe2O3) and magnetite (Fe3O4)) are the two most important minerals in these deposits. Hematite is commonly regarded as one of the most important iron ores due to its high-grade iron concentration and abundance. High-quality iron ore, often known as direct shipping ore, contains more than 60% hematite or magnetite.
Some Chinese end-users have seen some noticeable demand for very low grade products around the 50%-55% Fe range due to current high iron ore prices, another international trader said. However, utilization of these products are very limited due to high contaminant levels and supply for these products from the Goa stockpile or Indonesia tend to ...
