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.

The Fission Process | MIT Nuclear Reactor Laboratory
The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below). Each time a U-235 nucleus splits, it releases two or three neutrons.

Conventional Uranium Mills | NRC.gov
A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore.
