Uranium is obtained commercially from the extraction and processing of uranium-bearing minerals such as uraninite. The ores are processed through grinding to a uniform particle size and then treating with acid to chemically leach the uranium from the ore.

Uranium processing, preparation of the ore for use in various products. Uranium ores occur in deposits that are both near-surface and very deep (e.g., 300 to 1,200 metres, or 1,000 to 4,000 feet). The deep ores sometimes occur in seams as thick as 30 metres. As is the case with ores of other metals ...

Uranium Recovery (Extraction) Methods 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.

From February 2012 the extraction price is CFA 73,000/kgU ($145/kgU), paid in Euros. The partners then sell or use it, in the case of the government, through a trading company.
