· · The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore. Run of mines ores after dry or wet sizing, if it contains normally greater than 62 % of Fe, are known as 'natural ore' or 'direct shipping ore.
Iron ore resources can vary widely in grade, from 67 per cent Fe for the highest grade hematite DSO ores typical of Vale Brazil's Northern System and BHP's Mt Whaleback mine, to less than 20 per cent Fe for the majority of China's low grade magnetite Tonnages need to be normalised for Fe content to enable valid resource size comparisons. Although not an exporting .
