  • Iron Ore Pelletizing Process: An OverviewIntechOpen

    Jul 11, 2018However, the content of iron ore in deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the enrichment by separation after liberation by size reduction must be agglomerated in a pelletizing plant. Consequently, the number of pelletizing plants is expected to increase in the future.
