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.

The first comminution stage in a mineral processing plant is crushing, which reduces the size of particles from up to 1 m down to 0.5 cm (depending on the type of milling circuit). Crushing is typically a dry process that makes use of Gyratory, Jaw, and Cone crushers (Napier-Munn et al., 1996), which predominantly make use of impact …

Some other key drivers in flowsheet selection at the hashing stage are: Supergene weathering. This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold …
