Uranium Mining and Refining
Uranium, a common ore found in the earth's crust, is extracted for
use as nuclear fuel in nuclear reactors. Concentrations of uranium
are found mainly in North America, Australia, Southern Africa and
Central Asia.
The ore (which contains many other minerals) is mined and
transported to the uranium mills, normally on the mine site. Here,
the ore is ground into a powder and the uranium is separated and
purified to produce a dry powder of uranium oxide known as uranium
ore concentrate (UOC). These concentrates, generally known as
"yellow cake" because of their colour, are then transported (by
rail, road and sea) in sealed 210 litre drums in standard sea
freight containers to chemical conversion plants.
