uranium ore milling process

May 15 2017 · Conventional Uranium Mills At the heart of the NRCs regulatory definition of uranium milling is the concept of the mill tailings produced by the extraction and concentration of uranium Mill tailings are the finegrained sandy waste byproduct material that remains after the milling process has extracted and concentrated the uranium from the ore
