Hard rock hematite deposits often require a combination of milling, screening and on occasion, fine classification to prepare a finely sized ( 1.0mm), liberated feed for beneficiation by gravity separation. This is typically followed by re grinding of the tailings to liberate more hematite for further iron unit recovery by magnetic separation.
