The end product of a uranium development project is a saleable uranium concentrate. Saleability is determined by the acceptance of the market to buy the product at a price which provides a net positive benefit. Bringing a uranium operation into production involves a sequence of interrelated steps. These are outlined in the simplified diagram of ...

Uranium ores, concentrates, calcines or tailings are processed to remove radium and thorium as well as uranium. Selected ores, concentrates or tailings, or if more appropriate, chlorination calcines thereof, are leached by selected aqueous chlorinecontaining media (preferably in two stages) until uranium, radium and thorium are substantially all dissolved, with the insoluble …

Uranium milling is the process of extracting and purifying uranium ore concentrates (UOC) from uranium-rich geological deposits. On the order of 62,071 tons of uranium were produced worldwide in 2016 by commercial U mills; Kazakhstan's and Canada's production combined to account for over 62% of the total annual production (Grancea et al., 2018).

Alternatively, uranium may be recovered from the ore using a heap leach process. In the heap leach process, the ore is placed on a engineered barrier and sprayed with acid. The uranium dissolves into solution and is collected at the engineered barrier. The solution undergoes additional chemical processing to produce "yellowcake".

Uranium processing - Leaching, Extraction, Purification: 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. Acid leaching is commonly performed …
