Specific mechanism of Acidithiobacillus caldus extracellular polymeric substances in the bioleaching of copper-bearing sulfide ore.

PLoS ONE, 2019
This study aimed to reveal the specific mechanism of extracellular polymeric substances (EPS) in the bioleaching of copper-bearing sulfide ore by moderately thermophilic bacterium Acidithiobacillus caldus. The bioleaching performance of blank control (BC)

The promotion effect of FeS2 on Sb2S3 bioleaching and Sb speciation transformation

Frontiers in Microbiology
Stibnite (Sb2S3) is an important but difficult to biologically leach mineral, so it is important to find a potential scheme for improving the bioleaching rate of Sb2S3.
