Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. A conventional uranium mill is a chemical plant that extracts uranium using the following process: Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached).

Uranium Mining and Milling Wastes: An Introduction

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. As the leaching agent not only extracts uranium from the ore, but also several other constituents like molybdenum, vanadium, selenium, iron, lead and arsenic

Milling and Processing How Uranium Mining Works

15/11/2011 After milling, other companies will buy the uranium to enrich it, or increase the ratio of the isotope U-235 in a given sample. During enrichment, scientists convert the yellowcake (uranium oxide) to uranium hexafluoride gas, which is put in cylinders to become a solid when it cools [source: NRC]. To enrich uranium enough to be used as nuclear fuel, workers will increase the concentration of U
