Uranium Milling | nuclear-power

Uranium milling is a series of mechanical and chemical processes, which processes extracted uranium ore and produces dry powder-form material consisting of natural uranium, which is called “ yellowcake ” (chemically U 3 O 8) because of its yellowish color. Uranium ores are normally processed by grinding the ore materials to a uniform ...

Mining and milling - ScienceDirect

2020-1-1 · During milling the uranium bearing ore is initially crushed (if preceded by conventional mining), which is typically a dry process, and then ground into a slurry, which is a wet process. The intent of crushing and grinding is to effectively increase the surface area to volume ratio of the material, which facilitates chemical leaching.
