6. URANIUM TECHNOLOGY AND PROCESSES

6. URANIUM TECHNOLOGY AND PROCESSES

An innovative dual cycle extraction process has been developed at laboratory and pilot plant scale for extraction of hexavalent uranium from 4-6 M phosphoric acid. The process incorporates selective scrubbing of co-extracted rare earths in second cycle, followed by two stage precipitation to yield high purity yellow cake.

As a result of the recent price run-up for uranium, CF Industries has decided it is economically feasible to build a uranium extraction facility at its Plant City Phosphate Complex. The new facility will be able to produce about 900,000 pounds [346 t U] of uranium a year. CF expects uranium extraction to begin in three to four years.

Nuclear reprocessing - Wikipedia

Nuclear reprocessing - Wikipedia

Nuclear reprocessing is the chemical separation of fission products and unused uranium from spent nuclear fuel. Originally, reprocessing was used solely to extract plutonium for producing nuclear weapons. With commercialization of nuclear power, the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors.
