Uranium Mining And Milling Wastes An Introduction

The main types of waste generated by the mining and milling of uranium ore are tailings and waste rock. Tailings are the waste produced by grinding the ore and the chemical concentration of uranium. When dried tailings have the consistency of fine sand. Waste rock is simply rock material removed from the mine to gain access to the ore.
