01-07-2018  A large fraction (47%) of the world's uranium is mined by a technique called “In Situ Recovery” (ISR). This mining technique involves the injection of a leaching fluid (acidic or alkaline) into a uranium-bearing aquifer and the pumping of the resulting solution through cation exchange columns for the recovery of dissolved uranium.

MICROBIAL MINING - Spaceship Earth

In recent years bacterial leaching has also been applied to the recovery of another nonferrous metal: uranium. Recent progress in the genetic manipulation of microorganisms for industrial purposes promises to revitalize not only the bacterial leaching of metal-bearing ores but also the microbiological treatment of metal-contaminated waste water.

Bioreduction of Uranium Using Microbial Biomass

The most practical method financial is often the microbial treatment to remove uranium from waters, and here I will describe the basis in which that happens. [1] In Germany, there has been a lot of uranium mining and milling between 1952 and 1989 that produced around 231,000 tons of uranium.

Uranium mining - Wikipedia

Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tonnes per year included Namibia, Niger, Russia, Uzbekistan, the United

Biomining - Wikipedia

Iron-and sulfur-oxidizing microorganisms are used to release copper, gold and uranium from minerals. Electrons are pulled off of sulfur metal through oxidation and then put onto iron, producing reducing equivalents in the cell in the process. This is shown in this figure.

Uranium exists in several chemical forms in mining and mill tailings and in nuclear and weapons production wastes. Under appropriate conditions, microorganisms can affect the stability and mobility of U in wastes by altering the chemical speciation, solubility and sorption properties and thus could increase or decrease the concentrations of U in solution and the bioavailability.
