Uranium processing - Leaching | Britannica
Leaching. Roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. For the successful operation of all leaching systems, uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process.

Uranium Ore - an overview | ScienceDirect Topics
Uranium Ore Uranium ore has concentrations of uranium up to 1000 times the average concentration normally found in soil (NCRP, 1984) and can be exposed as a result of open-pit, in situ leach, or underground mining operations.
Increase Uranium Recovery by Nitric Acid Leaching
Chlorine-oxygen leaching extracted 63 pct of the uranium at a chlorine consumption of 46 lb/ton of ore and 79 pct at 164 lb/ton of ore. These experiments were conducted by reacting chlorine with an agitated concentrate-water slurry at 25° C for 1 hour. Oxygen then was administered, and the system was maintained at 100° C and 100 psig O2 for 24 hours.
Uranium Ore Processing Methods
The lime flotation concentrate would pass to a Thickener for dewatering prior to carbonate leaching to recover uranium. Underflow from the thickener would be metered by a Adjustable Stroke Diaphragm Pump. Flotation carried on at high density in Cells would eliminate subsequent thickening of the flotation tailings prior to leaching operations.
