Synergistic recovery of Pr, Eu, and Ce from gold mine tailings using bioleaching and oxalic acid pretreatment [PDF]

Scientific Reports
Mining activities produce a significant amount of gold mine tailings (GMT) rich in rare earth elements. Despite this, little information is available regarding the effective extraction of these precious elements from GMT. We describe a novel strategy for

Bioleaching Coal Gangue with a Mixed Culture of Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans [PDF]

Minerals, 2021
A mixed culture of A. ferrooxidans and A. thiooxidans isolated from a coal gangue dump was used to bioleach coal gangue in a column reactor to investigate the leaching of elements. The changes of metal ions (Fe, Mn and Cr) and sulfate in the leaching solution, elemental composition, mineral components and sulfur speciation of the coal gangue before and

Bioleaching Microbial Community Metabolism and Composition Driven by Copper Sulphide Mineral Type. [PDF]

Environ Microbiol Rep
Bioleaching is a microbially mediated green technology for the recovery of metals from ore. Here, microbial consortia from a copper bioleaching column in Cyprus were cultivated on chalcopyrite (CuFeS2) and then sub‐cultured on chalcocite (Cu2S) and chalcopyrite to investigate how mineral type and surface chemistry influence microbial community ...

Bioleaching and Kinetic Investigation of WPCBs by A. Ferrooxidans, A. Thiooxidans and their Mixtures [PDF]

Journal of Chemical and Petroleum Engineering, 2018
Bioleaching was used to mobilize Cu, Zn and Ni from waste printed circuit boards (WPCBs) and eliminate hazardous metal species from these wastes. Pulp density (PD) and medium culture are two effective factors which have been optimized in this paper.
