Bioleaching Microbial Community Metabolism and Composition Driven by Copper Sulphide Mineral Type

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
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 ...
