mining wet ball mill and leaching uranium ore :

Uranium Mining and Milling Wastes: An Introduction

2016-2-22  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
