Abstract

The present paper deals with the study on uranium (VI) leaching, as uranyl ions, from ores with a poor content in util minerals, using some algae as: Porphyridium cruentum (Smith and Soerly) Nägeli, Spirulina platensis CNM-CB-02 and Nostoc linkia (Roth) Born and Flah. The basic composition of these ores allowed the self-maintenance and self-development of these microorganisms, which have facilitated then the leaching of the uranium (VI) as UO2 2+ ions. The microbial leaching degree was comprised between 40–90%, depending on the used alga and experimental conditions.
