Conventional Uranium Mills NRC.gov

Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. 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).

Uranium Mining Overview World Nuclear Association. Milling and processing Conventional mines have a mill where the ore is crushed and ground to liberate the mineral particles then leached in tanks with sulfuric acid to dissolve the uranium oxides The solution is then processed to recover the uranium With some South African uranium recovery from gold tailings a pressure leach is necessary.

uranIuM MIllInG Milling is generally carried out close to a uranium mine. The mined uranium ore is crushed and chemically treated to separate the uranium. The result is 'yellow cake', a yellow powder of uranium oxide (U 3O 8). In yellow cake the uranium concentration is raised to more than 80%.

2019-11-30  Uranium occurs in many kinds of minerals in the earth’s crust. The nuclear industry distinguishes sometimes two categories of uranium resources, based on economic considerations: conventional and unconventional resources. The term ‘ore’ is an economic notion: only rock from which uranium can be extracted in a economic way is called ‘ore’.
