The process, which was well known to analytical chemists, became an industrial process during World War II, when it was used for such separations as zirconium/hafnium, uranium/vanadium, and plutonium purification. The first commercial solvent-extraction process for uranium was installed in 1955 at the Kerr-McGee plant in New Mexico.
