License: CC BY Uranium milling is a series of mechanical and chemical processes that process extracted uranium ore and produces dry powderform material consisting of natural uranium called " yellowcake " (chemically U 3 O 8) because of its yellowish color. Uranium ores are normally processed by grinding the ore materials to uniform ...

The product of uranium mining is normally uranium oxide concentrate U 3 O 8 which is shipped from the mines in 200litre drums. This is barely radioactive, but has chemical toxicity similar to lead, so occupational precautions are taken similar to those in a lead smelter. Most of the radioactivity from the ore ends up in the tailings.
