Abstract

ABSTRACT : R & D studies were carried out at NML using Acidithiobacillus ferrooxidans (Ac.TJ in
column for the bio-recovery of uranium from the low-grade uranium ore containing 0.024% U308 of
Turamdih Mines, Singhbhum. A recovery of 55 .48% uranium was obtained in bio-leaching as against --
44.0% in sterile control in 30 days at 1.7pH in a column containing 2 . 5kg ore of particle size mainly in the
ra,., 5-1mm . In the large scale column , leaching with 80kg ore of particle size -0.5cm, uranium biorecovery
was found to be 69.8% in comparison to a recovery of 55% in control set at 1.7 pH in 50 days. The
uranium recoveries followed indirect leaching mechanism.
