Uranium Mining And Milling Wastes An Introduction

URANIUM MINES Most uranium ore is mined in open pit or underground mines. The uranium content of the ore is often between only 0.1 and 0.2. Therefore, large amounts of ore have to be mined to get at the uranium. In the early years up until the 1960s uranium was predominantly mined in open pit mines from ore deposits located near the surface.
