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.
