BioBasics: Biomining
Today's modest, yet informative site, from the government of Canada, offers
an overview of the process of industrial "biomining". Some Gentle
Subscribers may be startled by the role played by microorganisms in a
sector more noted for enormous machinery than tiny organisms.
"Biomining is the use of microorganisms to extract metals and minerals from
ores in the mining process. ... The mining industry uses microorganisms and
their natural ability to digest, absorb, and change the quality of
different chemicals and metals, to refine ores." - from the website
The site provides a short synopsis of biomining, an explanation of chemical
processes involved - those of bioleaching and biooxidation and how these
procedures work. After a brief look at some of the shortcomings of this new
technology, the focus shifts to current research areas in biomining and its
role in sustainable development.
