Uranium Mining Overview

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.

Biomining

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

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.
