bioreactors for mineral processing

Mineral processing in bioreactors has become established in several countries during the past decade with industrial application of iron- and sulfur-oxidizing bacteria to release occluded gold from mineral sulfid Cobalt extraction in bioreactors has also been commercialized, and development of high-temperature biooxidation of copper sulfides.

Upstream Processing Upstream processing is the phase where cells are formulated and grown in the bioreactors. It includes all the steps related to inoculum development, media development, optimization of growth kinetics, and the like. After the product has been developed within the bioreactor, it's time for the harvesting stage. Harvesting

Mineral processing in bioreactors has become established in several countries during the past decade with industrial application of iron- and sulfur-oxidizing bacteria to release occluded gold from mineral sulfides. Cobalt extraction in bioreactors has also been commercialized, and development of high-temperature biooxidation of copper sulfides has reached pilot-plant scale. A variety of ...

This scientific paper provides a brief introduction into the use and development of industrial mineral-processing bioreactors and reviews the variety of microfloral species used in bioreactors. Additionally, the authors discuss recent microbiological and process developments with thermoacidophiles that could expand the range of mineral sulfides ...

Bioreactors For Mineral Processing. Bioreactors can be used to treat any contaminant that can be degraded anaerobically Hence contaminants including chlorinated ethenes and polycyclic aromatic hydrocarbons PAHs and munitions constituents such as trinitrotoluene TNT and 135trinitro135triazine Royal Demolition Explosive RDX oxidizers such as perchlorate and nitrate and dissolved metals such …

Similar bioreactors can also be used to generate ferric iron as an oxidant for indirect mineral processing, though because of the larger concentrations of ferric iron and lower pH of the liquors required, Leptospirillum spp. (rather than At. ferrooxidans and "Ferrovum myxofaciens") are more appropriate iron-oxidizing bacteria in this ...
