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 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.

Rock phosphate solubilization by abiotic and fungal‐produced oxalic acid: reaction parameters and bioleaching potential

Microbial Biotechnology, Volume 15, Issue 4, Page 1189-1202, April 2022., 2022
This research investigates the extraction of phosphate from rock phosphate by abiotic and fungal‐produced oxalic acid. Complete P extraction was achieved at stoichiometric proportions of apatite and oxalic acid, with up to 75% P released in less than 1 h.
