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 deposits.3 Tonnages need to be normalised for Fe content to enable valid resource size comparisons.

26.06.2012Phosphorus (P) and sulphur (S) are considered to be contaminants in iron ores. More specifically, phosphorus lowers the solidification temperature, increases fluidity, and renders the metal very fluid indirectly through the production of a low melting constituent in iron and steel making [ 18 ].
