Separation of uranium by biosorption
First Claim
1. A process for the extraction of uranium- and/or thorium-containing cations from aqueous suspension or solution, which comprises contacting an aqueous solution or suspension containing at least one of said cations with an effective amount of a biomass effective to absorb large quantities of at least one of said cations, said biomass being derived from the growth of a Rhizopus fungal microorganism.

Abstract
Uranium or thorium cations are removed from aqueous suspension or solution by treatment of the aqueous material with the biomass derived from fermentation of a fungal microorganism of the genus Rhizopus, e.g. Rhizopus arrhizus. The process can be utilized to treat aqueous tailings from uranium ore extraction processes, to reduce the radioactive content of the tailings prior to disposal.
