Bioleaching Modeling—A Review

Materials, 2023
The leaching of minerals is one of the main unit operations in the metal dissolution process, and in turn it is a process that generates fewer environmental liabilities compared to pyrometallurgical processes. As an alternative to conventional leaching methods, the use of microorganisms in mineral treatment processes has become widespread in recent ...

Advances in bioleaching of waste lithium batteries under metal ion stress

Bioresources and Bioprocessing, 2023
In modern societies, the accumulation of vast amounts of waste Li-ion batteries (WLIBs) is a grave concern. Bioleaching has great potential for the economic recovery of valuable metals from various electronic wastes.

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 ...
