Conventional Uranium Mills NRC.gov

Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. 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).

THE NUCLEAR FUEL CYCLE International Atomic Energy

2018-10-22  Mining and Milling — from Mined Uranium to Yellow Cake The raw material for today’s nuclear fuel is uranium, which is a relatively common metal that can be found throughout the world. Uranium is present in most rocks and soils, in many rivers and in sea water. Uranium is about 500 times more abundant than gold and about as common as tin.

2014-6-4  uranIuM MIllInG Milling is generally carried out close to a uranium mine. The mined uranium ore is crushed and chemically treated to separate the uranium. The result is ‘yellow cake’, a yellow powder of uranium oxide (U 3O 8). In yellow cake the uranium concentration is raised to more than 80%.

2002-3-11  For mining and milling of uranium a distinction is made between conventional mining and in situ leach (ISL) mining. A conventional mining operation consists of underground/or open pit operation and a process plant to extract the uranium from the host rock. An ISL operation consists of well fields and a process plant to extract the uranium.

Milling The process of milling extracts uranium from the ore produced in the mine. It is carried out close to the mine and produces a uranium concentrate generally called “yellow cake” which is cheaper to transport. The yellow cake typically contains more than 60% of uranium. The chemical process employed is termed leaching.
