Conversion

The alternative, 'dry' process is used in the USA. In the dry process, uranium oxide concentrates are first calcined (heated strongly) to drive off some impurities, then agglomerated and crushed. At Converdyn’s US conversion plant, U 3 O 8 is first made into impure UF 6 and this is then refined in a two-stage distillation process.
