▪ Abstract The use of acidiphilic, chemolithotrophic iron-and sulfur-oxidizing microbes in
processes to recover metals from certain types of copper, uranium, and gold-bearing …

This review describes the historical development and current state of metals leaching and
sulfide mineral biooxidation by the minerals industries. During the past 20 years commercial …

Bioleaching is an emerging technology with significant potentials to add value to the mining
industries so as to deliver attractive environmental and social benefits to all the associates …

Biomining is the use of microorganisms to extract metals from sulfide and/or iron-containing
ores and mineral concentrates. The iron and sulfide is microbially oxidized to produce ferric …

Background A variety of chemoautolithotrophic bacteria which are capable of oxidizing iron-
or sulphur-containing minerals may be readily isolated from acidic mine drainage or places …

Microorganisms were enumerated and isolated on selective solid media from a pilot-scale
stirred-tank bioleaching operation in which a polymetallic sulfide concentrate was subjected …

The ability to quantify the number and kinds of microorganisms within a community is
fundamental to the understanding of the structure and function of an ecosystem. The simple …

Microorganisms are important in metal recovery from ores, particularly sulfide ores. Copper,
zinc, gold, etc. can be recovered from sulfide ores by microbial leaching. Mineral …

Microbial populations, their distributions, and their aquatic environments were studied over a
year (1997) at an acid mine drainage (AMD) site at Iron Mountain, Calif. Populations were …

Bioleaching is the biological conversion of an insoluble metal compound into a water
soluble form. In case of metal sulfide bioleaching, metal sulfides are oxidized to metal ions …
