Sulphuric acid is the most preferred leachant for the recovery of
uranium from ores because it is cheap, less corrosive, and produces
anionic uranyl complex, which makes the separation of uranium from
other cationic gangue mineral easy using an anionic exchanger
subsequently. Sulphuric acid leaching of Narwapahar (INDIA) uranium
ore assisted with acoustic cavitation and without cavitation has been
studied. The primary uranium minerals of Narwapahar ore are uraninite
and pitchblende with minor presence of brannerite, allanite, xenotime,
and davidite. In this paper, we have discussed selective leaching of
uranium using sulphuric acid from Narwapahar uranium ore relative to
other leachable compounds and material balance has been carried out
around each of the leaching experiments. Material balance of uranium
ore and also that of uranium leaching for with and without cavitation
could be established within 
uranium, leaching, cake washing, acoustic cavitation.
