uranium processing - Leaching Britannica

This hydrofluorination process is usually performed in a fluidized-bed reactor. Conversion to uranium metal is accomplished through the Ames process, in which UF 4 is reduced with magnesium (Mg) at temperatures exceeding 1,300° C (2,375° F). (In an often-used modification of the Ames process, calcium metal is substituted for magnesium.)

AUSTRALIA'S URANIUM MINES – Parliament of Australia

The ion exchange section of the processing plant was replaced with a more effective solvent extraction process and the mine and mill reopened in February 1976 at a cost of $26 million. The mine was depleted at the end of 1982 and ceased operation after 4 802 tonnes of uranium oxide concentrate had been produced in its second phase of operation.

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 ...
