Uranium is a naturally occurring radioactive element used for fuel in nuclear power reactors. Canada, one of the world's largest uranium producers, accounts for 18 percent of global production and exports 90 percent of its uranium. Uranium is mined so it can be processed at a milling facility in order to recover the uranium concentrate.
Uranium Recovery (Extraction) Methods | NRC.gov
Uranium recovery involves one of the following extraction processes. In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits. The ore is transported to a mill, where it is crushed and undergoes a chemical process to remove the uranium.
Nuclear Fuel
Before uranium goes into a reactor, it must undergo four major processing steps to take it from its raw state to usable nuclear fuel: mining and milling, conversion, enrichment and fuel fabrication. First, uranium is mined with conventional methods or by in-situ leach mining, where carbonated water is shot into underground deposits and piped up ...

THE NUCLEAR FUEL CYCLE
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.

Waste Guide for the Uranium Milling Industry
The magnitude of liquid waste flows from uranium mills is greatly dependent upon the milling process used and the extent to which solutions are recirculated within the mill. In some cases the amount of water used is partially determined by the availability of water from local sources.
Uranium mining (open cut and underground) and milling ...
Uranium ore concentrate (UOC) is a general term to describe the final product of uranium mining and milling, although the term "yellowcake" is still loosely used. In fact, UOC may be yellow (eg, ammonium diuranate, uranyl peroxide), dark green-black, grey (U 3 O 8 ), ( Fig. 6.8 ), and sometimes orange.
