2014-10-23  This makes bio-oxidation a more expensive process than bioleaching and so is almost solely used for extracting gold. Other differences between bio-oxidation and bioleaching are that the former works with a gold-rich concentrate chemically extracted from the rock and releases the gold as tiny solid particles rather than dissolved in a leachate.

2008-12-11  Acidithiobacillus ferrooxidans is a major participant in consortia of microorganisms used for the industrial recovery of copper (bioleaching or biomining). It is a chemolithoautrophic, γ-proteobacterium using energy from the oxidation of iron- and sulfur-containing minerals for growth. It thrives at extremely low pH (pH 1–2) and fixes both carbon and nitrogen from the atmosphere.

Heavy Metal Resistance Strategies of Acidophilic

Microbial solubilizing of metals in acid environments is successfully used in industrial bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others. This is done mainly by acidophilic and other microorganisms that mobilize metals and generate acid mine drainage or AMD, causing serious environmental problems.
