Iron Ore an overview ScienceDirect Topics

Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe. ROM ore at 400–600 mm is fed to a primary crusher with product set at –40 mm. The crushed product is screened in two stages. The overflow of the first screen (+40 mm) is recrushed.
