uranium processing Britannica

2021-8-22  The hydrometallurgical processing of uranium ores is frequently preceded by a high-temperature calcination step. Roasting dehydrates the clay content of many ores, removes carbonaceous materials, oxidizes sulfur compounds to innocuous sulfates, and oxidizes any other reductants that may interfere in subsequent leaching operations.

uranium processing - Leaching Britannica

uranium processing - uranium processing - 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. Acid leaching is commonly performed by agitating an ore ...

2020-9-1  1. Introduction. 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).

PRESENT SITUATION OF THE URANIUM ORE PROCESSING

Conventional processing produces only partial uranium recovery from these ore materials. Ore samples from New Mexico, Texas, and Wyoming were examined, and each responded differently. Using direct acid leaching techniques, some of the ores required acid additions of only 50 pounds per ton, while others required 300 pounds per ton of material.
