2015-6-3 · In the case of the Homestake Pitch uranium mine, pit excavation near the fault on the northeast slope led to a series of slope failures soon after mining started in 1977 and continuing through to 1980. In 1983 extreme climatic conditions led to an excess accumulation of water which weakened the northeast slope and led to the failure shown in

Uranium Mining and Milling Wastes: An Introduction

2016-2-22 · 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.

Thorium

Thorium is much more abundant in nature than uranium. Thorium can be used as a nuclear fuel through breeding to uranium-233 (U-233). When this thorium fuel cycle is used, much less plutonium and other transuranic elements are produced, compared with uranium fuel cycles. Several thorium-fuelled reactor concepts are under consideration.
