Ore Pretreatment or Beneficiation. A process step that may precede conventional agitation leaching and possible heap leaching is ore pretreatment, or "beneficiation," in order to reduce the quantity of ore that will require chemical treatment. Beneficiation involves separating some of the host rock from the uranium-bearing mineral.
