Bio-processing of solid wastes and secondary resources for metal extraction - A review.
Jae-chun Lee,Banshi Dhar Pandey +1 more
TL;DR: This review focuses on the bio-processing of solid wastes/byproducts of metallurgical and manufacturing industries, chemical/petrochemical plants, electroplating and tanning units, besides sewage sludge and fly ash of municipal incinerators, electronic wastes (e-wastes/PCBs), used batteries, etc.
BookDOI
Microbial Processing of Metal Sulfides
TL;DR: The present work focuses on the application of bioinformatics and genome biology to advance the understanding of bioleaching microorganisms, as well as other applications, including bioflotation and bioflocculation of relevance to minerals.

Comparative study on the bioleaching of zinc sulphides
TL;DR: In this article, a bio-leaching process of three zinc sulphides (marmatite, sphalerite and ZnS synthetically prepared) with acidithiobacillus ferrooxidans and a moderately thermoacidophilic iron-oxidizing bacterium (MLY) was investigated by leaching experiments and electrochemical methods.

The role of Thiobacillus ferrooxidans in hydrometallurgical processes
TL;DR: In this paper, the authors illustrate the increased interest which is manifested in the microorganisms, Thiobacillus ferrooxidans, involved in the biohydrometallurgical extraction processes.
Journal ArticleDOI
Molecular genetics of Thiobacillus ferrooxidans
TL;DR: The most recent studies have focused on the molecular genetics of the pathways associated with nitrogen metabolism, carbon dioxide fixation, and components of the energy-producing mechanisms of T. ferrooxidans.
Journal ArticleDOI
Bioleaching of molybdenum from coal liquefaction catalyst residues
TL;DR: In this paper, it has been shown that the bacterium Thiobacillus ferrooxidans can solubilize MoS2 from coal liquefaction catalyst residues, in which form it can be recovered as a soluble or HCl extractable material.
Journal ArticleDOI
Copper removal from an industrial waste by bioleaching
Thomas R. Clark,Henry L. Ehrlich +1 more
TL;DR: Copper contained in a solid industrial waste produced in a silicone manufacturing process was leached with spent iron medium from a Thiobacillus ferrooxidans culture, and removal of the copper from the waste appeared to involve its displacement by acid, dissolved mineral salts, and ferric iron.
Journal ArticleDOI
Analysis of molybdenite bioleaching by Thiobacillus ferrooxidans in the absence of iron (II)
TL;DR: Data confirm the need of bacterial attachment to insoluble substrate forBioleaching by the direct mechanism and suggests that the poor bioleaching of MoS2 is caused by its hydrophobic character.
