  • Uranium Mining and Milling Wastes: An Introduction

    May 18, 2011 · 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 1960''s uranium was predominantly mined in open pit mines from ore deposits loed near the surface.
