Conversion - World Nuclear Association

Conversion ProcessSecondary Sources of Conversion SupplyDepleted Uranium and DeconversionThe main, 'wet' process, is used by Cameco in Canada, by Areva in France, at Lanzhou in China and Seversk in Russia. For the wet process, the concentrate is first dissolved in nitric acid. The resulting clean solution of uranyl nitrate UO2(NO3)2.6H2O is fed into a countercurrent solvent extraction process, using tributyl phosphate dissolved in kerosene or dodecane. The uranium is collected by the organic extractant, from which it can be washed out by dilute nitric acid solution and then conce...
