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.  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 Overview. (Updated December 2020) In the last 60 years uranium has become one of the world''s most important energy minerals. It is mined and concentrated similarly to many other metals. While uranium is used almost entirely for making electricity, a small proportion is used for the important task of producing medical isotopes.
· Mining for uranium with ISR occurs in locations where the ore is deposited within a sedimentary rock or sediment layer with a relatively high hydraulic conductivity (e.g., sandstone) that lies between two relatively impermeable layers, and preferably below the).
· Uranium ore diagenesis studied in many locations has been found to have begun with organic matter complexation, microbial reduction, and finally transformation to U and metal sulphides. The ecological approach proposed for the removal of U from waste water follows these natural steps.
· An old mine spoil at a 19th-century mining site with considerable residues of uranium (400–800 mg U/kg) was investigated with respect to U concentrations in soil and plants and tolerance to U in the soil microbial community in order to describe the bioavailability of ...
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. ...

· Uranium has been mined using underground mining, open pit mining or in situ recovery (ISR) methods from a great diversity of deposits (Cuney, 2009). Over the past two decades, the use of ISR has been progressively increasing and now accounts for 45 % of the worlds U production ( World Uranium Mining Production: World Nuclear Association, 2012 ).

Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.

Microbial Mining. Home. This website is dedicated to the use of microbes in the mining of metals such as Iron, Copper and Uranium. In short, the main use of microbes in mining is in microbial leaching. This is the process whereby a microbe will reduce or oxidise an insoluble metal into a soluble form, which can then be extracted and used by us.
