Estudo da dissolução oxidativa microbiológica de uma complexa amostra mineral contendo pirita (FeS2), pirrotita (Fe 1-XS) e molibdenita (MoS2)
(2007-09-01)
This work aims to study the oxidation of a complex molybdenite mineral which contains pyrite and pyrrotite, by Acidithiobacillus ferrooxidans. This study was performed by respirometric essays and bioleaching in shake flasks. ...

Environmentally sustainable and cost-effective bioleaching of aluminum from low-grade bauxite ore using marine-derived Aspergillus niger
(2020-08-01)
In this study, an economical and sustainable bio-hydrometallurgical route was evaluated for the recovery of aluminum from low-grade bauxite using the marine-derived fungus Aspergillus niger. Firstly, four different solid ...
Genome analysis of species of the new bioleaching acidophilic bacterial genus Acidiferrobacter.
(2017)
Biomining is the use of microorganisms for the industrial extraction of valuable metals and
treatment of mine waste. Acidiferrobacter is a recently described genus of bioleaching bacteria.
These are ca. 2 μm long and ca. ...
A new genome of Acidithiobacillus thiooxidans provides insights into adaptation to a bioleaching environment
(2014)
Acidithiobacillus thiooxidans is a sulfur oxidizing acidophilic bacterium found in many sulfur-rich environments. It is particularly interesting due to its role in bioleaching of sulphide minerals. In this work, we report ...
Effects of pollution and bioleaching process on the mineral composition and texture of contaminated sediments of the Reconquista River, Argentina
(Springer Heidelberg, 2017-10)
In this work, we report on the structural and textural changes in fluvial sediments from Reconquista River´s basin, Argentina, due to processes of contamination with organic matter and remediation by bioleaching. The ...
Electrochemical noise analysis of bioleaching of bornite (Cu5FeS4) by Acidithiobacillus ferrooxidans
(Elsevier B.V., 2006-09-01)
Electrochemical noise (EN) is a generic term describing the phenomenon of spontaneous fluctuations of potential or current noise of electrochemical systems. Since this technique provides a non-destructive condition for ...

The bioleaching potential of a bacterial consortium
(Elsevier, 2016)
This work presents the molecular foundation of a consortium of five efficient bacteria strains isolated from copper mines currently used in state of the art industrial-scale biotechnology. The strains Acidithiobacillus ...
