Bioleaching of uranium minerals and biosynthesis of UO2 nanoparticles

Baranska J. A., Sadowski Z.

Physicochemical Problems of Mineral Processing

2013

Vol. 49, iss. 1

71--79

Uranium mining has resulted in generation of significant amounts of solid wastes. The mecha-nism and chemical conditions of uranium waste bioleaching were considered. The initial results of bi-oleaching of solid waste from closed Kowary mine were presented. The process of U(VI) bioreduction by anaerobic reduction microorganisms was described. The factors that contributed to UO2 nanoparticles fabrication were discussed. The obtained UO2 particles are promising for development of novel catalysts.
