Currently more than 90% of the world's copper is obtained through sulfide mineral
processing. Among the copper sulfides, chalcopyrite is the most abundant and therefore …

Sulfobacillus thermosulfidooxidans strain Cutipay is a mixotrophic, acidophilic, moderately
thermophilic bacterium isolated from mining environments of the north of Chile, making it an …

Bioleaching is an emerging technology, describing the microbially assisted dissolution of
sulfidic ores that provides a more environmentally friendly alternative to many traditional …

The study and development of new sustainable mining methods to exploit low-grade ores
and secondary metallic resources are essential to meet global demand and contribute to …

A moderately thermophilic and acidophilic sulfur-oxidizing bacterium named S 2, was
isolated from coal heap drainage. The bacterium was motile, Gram-negative, rod-shaped …

Thermoacidophiles can exist in a state of dormancy both in moderate temperatures and
even in cold conditions in heap leaching. Sulphide mineral ores such as chalcopyrite …

Biomining is the extraction of target metals from ores or wastes such as the dissolution of
chalcopyrite for copper recovery. A key outstanding topic of study is to improve the rate and …

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 …

In recent years, bacterial leaching of copper from low grade chalcopyritic ores has been
adverted very much. Different parameters such as the type of microorganisms, pH …

Selective enrichments enabled the recovery of moderately thermophilic isolates with copper
bioleaching ability from a spent copper sulfide heap. Phylogenetic and physiological …
