Uranium Mining and Milling Wastes: An Introduction
Ore mined in open pit or underground mines is crushed and leached in a uranium mill. A uranium mill is a chemical plant designed to extract uranium from ore. It is usually located near the mines to limit transportation. In the most cases, sulfuric acid is used as the leaching agent, but alkaline leaching is also used.

Mining Milling Conversion and Enrichment of Uranium Ores
Uranium as mined cannot be fed directly into a nuclear power station in contrast to coal, gas, or oil in a fossil-fueled power station. Uranium ore contains mineral and chemical impurities including radioactive daughter products of uranium. The uranium consists of 0.7% uranium-235 and 99.3% of uranium-238 isotopes.

Where Does Uranium Come From?
Mining and Milling: From Ore to Yellowcake. Uranium miners employ several techniques: surface or open-pit mining, underground mining, and in-situ recovery mining, which involves using liquids to recover minerals from underground ore. Uranium also can be a byproduct of other mineral processing operations.
