stages of uranium extraction in the milling process

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.

Therefore, a number of chemical and physical separation processes are required to convert uranium ore into optimized nuclear fuel elements through the stages of mining, milling, conversion, and enrichment. These form the “FRONT END” of the nuclear fuel cycle.

Mining Milling - Cameco U101

Uranium ore is simply rock with elevated amounts of uranium in it. Once the rock has been removed by open pit or underground mining it must be milled to separate the uranium from other constituents. The milling process for uranium is similar to that used for other metals such as copper, gold or nickel.

Most mining facilities include a mill, although where mines are close together, one mill may process the ore from several mines. Milling produces a uranium oxide concentrate, which is shipped from the mill. In the milling process, uranium is extracted from the crushed and ground-up ore by leaching, in which either a strong acid or a strong ...
