Phosphate beneficiation in Florida generates more than one tonne of phosphatic clay, or slime, per tonne of phosphate rock produced. Since the start of the practice of large-scale washing and desliming for phosphate beneficiation, more than 2 Gt of slime has accumulated, containing approximately 600 Mt of phosphate rock, 600 kt of …

There is good potential to significantly upgrade the uranium plant feed grades by sizing and gravity separation, achieving beneficiation from 0.01% to 0.55% U 3 O 8, and increasing the leach feed grade accordingly. The uranium occurs as carnotite of a particular particle size, significantly denser than the host gangue, mainly calcite.

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 …
