Sometimes a physical beneficiation process is used to concentrate the ore and increase the head grade before chemical treatment. This may be radiometric sorting as at Ranger, screening/gravity, or a new process called ablation. Most of the ore is barren rock or other minerals which remain undissolved in the leaching process
