This review outlines current research in heap bioleaching, particularly in respect of the
bioleaching of chalcopyrite, assesses the status of the bioprocessing of copper sulphides …

Microorganisms are used in large-scale heap or tank aeration processes for the commercial
extraction of a variety of metals from their ores or concentrates. These include copper …

Arsenopyrite (FeAsS) is the most common As-bearing sulfide mineral. Under oxidising
conditions, such as those in mine waste systems, it breaks down to release acids of As and …

Abstract 'Ferroplasma acidarmanus' Fer1 is an arsenic-hypertolerant acidophilic archaeon
isolated from the Iron Mountain mine, California; a site characterized by heavy metals …

Two sets of arsenic resistance genes were isolated from the highly arsenic-resistant
Leptospirillum ferriphilum Fairview strain. One set is located on a transposon, Tn LfArs, and …

Acidophiles are microorganisms that thrive under highly acidic conditions (pH 3 or below)
and are distributed in the three domains of life: Archaea, Bacteria, and Eukarya. Among the …

The sulfur oxidation kinetics of an industrial strain of Acidithiobacillus caldus (At. caldus)
cultured on elemental sulfur was explored in batch experiments in the absence and …

A transposon, Tn AtcArs, that carries a set of arsenic-resistance genes was isolated from a
strain of the moderately thermophilic, sulfur-oxidizing, biomining bacterium Acidithiobacillus …

Brevundimonas sp. is a bacteria able to grow in metal (loid) contaminated soil from
Puchuncaví Valley, central Chile. This study has isolated a bacterial strain capable of growth …

Acidophilic microorganisms inhabit low pH environments such as acid mine drainage that is
generated when sulfide minerals are exposed to air. The genome sequence of the …
