Uranium Mining and Fuel - Nuclear Power Info

The Mining Process: There are three main methods of mining uranium, or any mineral for that matter. The first is open pit mining, also known as strip mining. It is a cheap mining method and also an extremely environmentally damaging process, as large swaths of earth are stripped away to reveal the mineral deposits.

Uranium Mining and Milling Wastes: An Introduction

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 located near the surface.
