Conventional Uranium Mills | NRC.gov - NRC Web

At the heart of the NRC's regulatory definition of uranium milling, is the concept of the mill tailings produced by the extraction and concentration of uranium. Mill tailings are the fine-grained, sandy waste byproduct material that remains after the milling process has extracted and concentrated the uranium from the ore.

In the Commission's fuel cycle rule, 10 CFR 51.20, Table S-3 summarizes the environmental effects of the uranium fuel cycle. In April 1978 the Commission deleted from Table S-3 the original radon-222 estimate which did not include long-term radon releases from uranium mill tailings piles or radon releases from uranium mining operations.

Uranium Milling Process. After extraction, the ores from both open pit and underground mines require milling. Machines crush and pulverize the rocks into fine fragments. Processors first add water and then sulfuric acid or an alkaline solution to release uranium from the rocks. This produces uranium oxide (or yellow cake).
