Microbiological control in uranium processing

Creators

Description

A method is described of improving the recovery of U/sub 3/O/sub 8/ from circulating aqueous leach fluids used to extract uranium from its ores in underground uranium fields. The fields are made up of a series of injection and producing wells. The aqueous fluids are contaminated by suspended and dissolved inorganic iron compounds caused by the presence of anerobic and anerobic bacteria. The method comprises treating such aqueous leach fluids with at least 0.1 ppm of a mixture of 75% of 5-chloro-2-methyl-4-isothiazolin-3-one and 25% 2-methyl-4-isothiazolin-3-one
