Extraction of Copper from Copper Concentrate by Indigenous Association of Iron-Oxidizing Bacteria

Separations
Bioleaching of Cu from the copper concentrate of Armanis gold-bearing polymetallic ore (Armenia) was investigated. The main objective was revealing high active bacteria and their association, as well as optimizing the bioleaching process with their ...

Nutrient optimization in bioleaching: are we overdosing?

Frontiers in Microbiology
The general trend in biomining (i.e., bioleaching and biooxidation) is the use of media with high concentrations of the nutrients (nitrogen as ammonium, phosphorous as phosphate, and K), which are considered to be essential for microbial growth.

Engineered Biopolymer Architectures for Selective Metal Ions Extraction

Advanced Sustainable Systems, Volume 10, Issue 4, April 2026.
This review establishes a mechanism‐oriented framework that connects biopolymer chemistry, structural engineering, ligand design, and hydrometallurgical process variables for selective metal‐ion extraction. It analyzes how functional groups, hierarchical architectures, and solution speciation govern adsorption capacity and selectivity in acidic ...

Use of large pieces of printed circuit boards for bioleaching to avoid ‘precipitate contamination problem’ and to simplify overall metal recovery

MethodsX, 2014
Very recently bioleaching has been used for removing metals from electronic waste. Most of the research has been targeted to using pulverized PCBs for bioleaching where precipitate formed during bioleaching contaminates the pulverized PCB sample and ...
