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.

Honeymoon Uranium Project, New South Wales, Australia

The uranium ore will be extracted using the in-situ recovery (ISR) method and will be processed using solvent extraction (SX) at a processing plant adjacent to the mine. The extraction of uranium ore will involve the injection of acidified leach solution into the ore zone (wellfield) through the injection wells.

United Nuclear - Uranium Extraction Experiment

Place the barrel on the mill and let it run for approximately 2 hours. This will reduce the ore into a very fine dust. This is necessary so the extraction chemicals will be able to react with the ore material. If Ball Milling is not done, very little Uranium will be extracted. After 2 hours of milling, the ore is as fine as Talcum powder.
