Iron Ore Pelletizing Process: An Overview IntechOpen

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process

Breakthrough technology for carbonfree, hydrogenbased

Currently, all available technologies require agglomeration, like pelletizing to produce DRI or HBI. An additional challenge steel producers face, is the reduced quality of iron ore, resulting in the need to beneficiate the iron ores. In order to progress to a CO 2 free steel production, a process using mainly H 2 is most desirable.
