Lithium bioleaching: An emerging approach for the recovery of Li from spent lithium ion batteries.

Chemosphere, 2021
The rapidly growing demand for lithium has resulted in a sharp increase in its price. This is due to the ubiquitous use of lithium-ion batteries (LIBs) in large-scale energy and transportation sectors as well as portable devices.

Comparison of bioleaching of a sulfidic copper ore (chalcopyrite) in column percolators and in stirred-tank bioreactors including microbial community analysis.

Chemosphere, 2023
Chalcopyrite is the most abundant Cu-sulfide and economically the most important copper mineral in the world. It is known to be recalcitrant in hydrometallurgical processing and therefore chalcopyrite bioleaching has been thoroughly studied for ...

A Comprehensive Review on Cobalt Bioleaching from Primary and Tailings Sources

Mineral Processing and Extractive Metallurgy Review, 2023
The production of critical metals for emerging clean technologies also requires more sustainable, cleaner and cost-effective processing options. The recovery of cobalt (Co) via pyrometallurgical or hydrometallurgical methods has proved to be successful ...

Metal extraction from spent lithium-ion batteries (LIBs) at high pulp density by environmentally friendly bioleaching process

, 2021
Spent lithium-ion batteries (LIBs) are more hazardous due to the presence of several toxic metals such as cobalt, lithium, nickel, manganese, etc. as well as electrolytes such as LiPF6, LiBF4, or LiClO4. However, these spent LIBs are the secondary source

Modeling continuous bioleach reactors

Biotechnology and Bioengineering, 1999
The results of recent research have shown that the bioleaching of sulfide minerals occurs via a two-step mechanism. In this mechanism, the sulfide mineral is chemically oxidized by the ferric-iron in the bioleaching liquor. The ferrous-iron produced is subsequently oxidized to ferric-iron by the microorganism.

Indirect bioleaching recovery of valuable metals from electroplating sludge and optimization of various parameters using response surface methodology (RSM).

Journal of Environmental Management, 2022
Electroplating sludge contains amounts of valuable/toxic metals as a typical hazardous solid waste, but existing technology is hard to simultaneously gain the high recovery of valuable metals and its convert into general solid waste.

Bioleaching of molybdenite

Hydrometallurgy, 2008
Abstract Molybdenum was bioleached from molybdenite-containing mine waste samples and from high purity molybdenite in solutions amended with ferrous sulfate. Bioleaching of Mo occurred when solution Eh exceeded 750 mV to 800 mV (s.h.e.). The rate of bioleaching of high purity molybdenite increased with decreasing particle size, averaging 3.22 mg Mo/m
