Uranium Ore. With the decreased market price of uranium beginning in the 1980s, U.S. producers turned increasingly to in-situ recovery (ISR) operations to extract uranium from ore. In-situ recovery (also known as "solution mining") is when fluids are injected into an ore-bearing aquifer to mobilize uranium, which becomes soluble in water.

Uranium is a naturally-occurring radioactive element that has been mined and used for its chemical properties for more than a thousand years. It is now primarily used as fuel for nuclear reactors that make electricity. Uranium can be recovered in two ways: by conventional mining of the rock (ore), or by using strong chemicals to dissolve uranium from the rock that is still in the ground and ...

A new process for extracting uranium from ores with carbonate solutions is described. Leaching is carried out under oxygen pressure to ensure that all the uranium is converted to the soluble hexavalent state. By this method, alkaline leaching can be used successfully to treat a greater variety of ores, including pitchblende ores, than has been possible in the past. The advantages of carbonate ...
