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 regrinding of the tailings to liberate more hematite for further iron unit recovery by magnetic separation.

tailings are used in dump or heap leaching, a process that the mining industry considers a form of beneficiation and one that involves spraying the material with acid or cyanide to leach out metals. This process is most widely practiced in the copper, silver, and gold mining segments, and the associated wastes are termed dumpheap leaching wastes.
