Overexpression of quorum sensing genes in Acidithiobacillus ferrooxidans enhances cell attachment and covellite bioleaching

Biotechnology Reports, 2023
Cell adhesion is generally a prerequisite to the microbial bioleaching of sulfide minerals, and surface biofilm formation is modulated via quorum sensing (QS) communication.

Leaching Behavior of Copper Sulfide Concentrate in Sulfate–Chloride Media With Hydrogen Peroxide and Ethylene Glycol

Engineering Reports, Volume 8, Issue 5, May 2026.
Copper sulfide concentrate leaching in sulfate–chloride media was significantly enhanced by chloride ions and stabilized hydrogen peroxide. Ethylene glycol suppressed oxidant decomposition at high temperature, increasing copper recovery to 75.2% and overcoming chalcopyrite passivation through a surface‐reaction‐controlled mechanism.
