Dec 03, 2011 Uranium as mined cannot be fed directly into a nuclear power station in contrast to coal, gas, or oil in a fossil-fueled power station. Uranium ore contains mineral and chemical impurities including radioactive daughter products of uranium. The uranium consists of 0.7% uranium-235 and 99.3% of uranium-238 isotopes.

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 1960's uranium was predominantly mined in open pit mines from ore deposits located near the surface.

uranium ore processing methods

The activities of ore processing include extraction of uranium from the mined rock, production of uranium oxide, and secure packing and shipment of the processed uranium. The mined ore is delivered to primary crushers by haul trucks and then by conveyor to the coarse ore stockpile. The process continues until the particles become smaller than 19mm.
