Cardinal Mill
Located about two miles west of Nederland in western Boulder County, the Cardinal Mill processed gold, silver, and tungsten ore from its parent mine, the Boulder County Tunnel, as well as other local mines between 1902 and 1942. The Cardinal Mill was an essential part of the area's tungsten boom in the early twentieth century and is a rare example of …

Nuclear fuel cycle' Extractingg uranium from its ores
5000 kg ore for each kilogram of uranium recovered. To produce the same amount of uranium, therefore, mill-size can vary by a factor of 10. Most uranium mills use wet grinding, and the resulting slurry is fed to a leaching circuit where sulphuric acid is added. Acid consumption does not depend on the uranium content of the ore, but is ...

Conventional Mining | Uranium Producers of America
Ore stockpiles are constructed to store sufficient ore volume to run the mill for a continuous period and to provide a "blend" of ore to ensure consistent feed to the mill. The first stage is crushing and grinding where the ore is reduced down to individual grains to ensure that the uranium mineralization is exposed to the leaching agents.
