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 low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …

17.1. Introduction. Iron making deals with the extraction of iron from ores because iron without processing is only available in meteorites. Iron is a principal component of steel (about 99.7%)—which is the most important construction material of today: world steel production made up in 2012 1548 Mt in comparison to 280 Mt of …
