Mining and milling - ScienceDirect

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.

Uranium — How Is It Mined?

Milling. For both traditional underground and open pit mining, the rocks may have only a few percent (normally <0.3%) uranium in them. The uranium then has to be removed from the rock and concentrated. The milling process involves crushing and pulverizing the rock into very fine fragments and adding water to create a slurry.

Uranium Mining Overview - World Nuclear Association

Milling and processing. Conventional mines have a mill where the ore is crushed and ground to liberate the mineral particles, then leached in tanks with sulfuric acid to dissolve the uranium oxides. The solution is then processed to recover the uranium. With some South African uranium recovery from gold tailings, a pressure leach is necessary.

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.
