Mining
When uranium is extracted, pitchblende is broken up
and mixed with sulfuric and nitric acids. It then dissolves
into uranyl sulfate. With the addition of sodium hydroxide,
uranium is precipitated as sodium diuranate which is
known as the yellow oxide of uranium. To get uranium
from carnotite, the ore must be finely ground and treated
with a hot solution of caustic and potash to dissolve out the
uranium, radium, and vanadium. And after the sandy matrix
is washed away, the solution is treated with sulfuric acid
and barium chloride. A caustic alkali solution is then added
to the remaining clear liquid precipitates the uranium and
radium into concentrated form.
