Iron Ore - an overview ScienceDirect Topics

The chemical composition of many fine iron ore products continues to decline with time as higher-grade reserves are replaced with lower-grade reserves for both direct-ship and beneficiated products. It is expected that this trend of declining iron ore product grades is most likely to continue well into the future. Lower-grade direct-ship products are likely to be slowly

When looking at the chemical composition of pellets, sinter, and lump ore (Table 1), it can be seen that the total amount of iron is over 50% in all materials. It was verified with FESEM that this iron comes from hematite and magnetite. This happens because of the characteristics of the sintering and pelletizing processes, as well as, in case of lump ore, wüstite not being present
