URANIUM ENRTCHMENT PLANT CHARACTERISTICS- A …
To provide feed material to an enrichment plant, uranium must be mined, milled, and converted to the appropriate chemical form used in enrichment operations. In the first step of the fuel cycle, uranium-bearing ore containing small quantities of U3O8 (e.g., <0.2 wt %) is mined. In the milling operation, the uranium is extracted from the ore.

An ore dressing process has been proposed for the efficient recovery of the phosphate as fertilizer, allied applications and for the extraction of uranium and gypsum from the source mineral. The phosphate rock occurs mainly in nodules, while some are found as pellets, especially in the southern part of the study area.

Uranium Milling and Processing. Once the ore is mined, it is typically milled on site into a uranium oxide concentrate, often known as "yellowcake". 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 alkaline solution is used to dissolve the uranium oxide.
