Many different species of acidophilic prokaryotes, widely distributed within the domains
Bacteria and Archaea, can catalyze the dissimilatory oxidation of ferrous iron or reduction of …

Fifty mesophilic and five moderately thermophilic strains of acidophilic heterotrophic bacteria
were tested for the ability to reduce ferric iron in liquid and solid media under aerobic …

Several anaerobic bacteria isolated from the sediments of Contrary Creek, an iron-rich
environment, produced magnetite when cultured in combinations but not when cultured …

Hydrometallurgical processes, of which bacterial leaching is a significant. part, are playing
an increasingly important role in the extraction of metals from low-grade ore minerals. The …

Abstract Ferric iron (Fe 3+) is an important low-cost oxidant in hydrometallurgical
processing. High-rate iron oxidation and removal of iron and sulphate from solution at low …

The susceptibility of various bacteriogenic iron oxides (BIOS) to bacterial Fe (III) reduction
was examined. Reduction resulted in complete dissolution of the iron mineral from the …

Biomining, as traditionally practised, uses aerobic, acidophilic microorganisms to accelerate
the oxidative dissolution of sulfide minerals present in ores and concentrates, thereby either …

A simple medium for the enumeration of iron-reducing bacteria, containing a readily
available iron source, ferric EDTA, was developed. Three cultures of iron-reducing bacteria …

Indigenous iron-oxidizing bacteria were isolated on modified selective 9KFe 2+ medium
from Baiyin copper mine stope, China. Three distinct acidophilic bacteria were isolated and …

Moderately thermophilic, iron-oxidizing acidophiles were enriched from coal collected from
an open-cut mine in Collie, Western Australia. Iron-oxidizers were enriched in fluidized-bed …
