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.
