The nuclear fuel cycle is an industrial process involving various activities to produce electricity from uranium in nuclear power reactors. Exploration for uranium is followed by mining and milling of the raw uranium ore. Raw uranium must then be processed, and sometimes enriched, in order to maximise its efficiency as fuel.

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.
