Uranium Mining and Milling Wastes: An Introduction
A uranium mill is a chemical plant designed to extract uranium from ore. It is usually located near the mines to limit transportation. In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used.

The History of Uranium Mining and the Navajo People
Uranium production in the northern and western Carrizo Mountains of the Navajo Nation, begun in 1948, peaked in the years 1955 and 1956 and declined to zero again by 1967.3, 19 More than 1000 abandoned uranium mines shafts are now estimated to lie on Navajo land (P. Charley, oral communication, 1995).
Nuclear Fuel Cycle | Department of Energy
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 alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.
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).

The surface miner is a mobile milling machine with a mechanically driven cutting drum. On Wirtgen machinery the drum is located between two sets of individually height adjustable crawler tracks, and a two- stage conveyor system used to directly load trucks. Wirtgen surface miners cut, crush and load the material in one single pass.
