Bioleaching - Wikipedia


Bioleaching is the extraction of metals from their ores through the use of living organisms. This is much cleaner than the traditional heap leaching using cyanide . [1] Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt .

In bioleaching application (the releasing of metals from ...


The leaching effectiveness depends largely on the efficiency of microorganisms and on the chemical and mineralogical composition of the ore to be leached.Among the bacteria,members of genus ...

In addition to organic acids, another interesting microbial process for metal leaching is the use of cyanogenic cultures. This process for Au leaching has been demonstrated by using cyanide lixiviants microbially produced from glycine [ 41, 42 ].

Residues from the mechanical recycling of used electronic equipment (e.g. computers) represent a highly complex metal-containing matrix (Brandl ., 2001). These solid wastes often contain metals with a high economic value. Particularly gold is of special interest and can occur in concentrations of 20 mg kg−1 shredded printed circuit boards. Gold-containing pieces (5 × 10 mm) of printed ...

The aim of this research was to compare the efficiencies of microbial leaching and chemical leaching of As and heavy metals from mine tailings. A mixed culture of Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans was used as a microbial lixiviant agent for microbial leaching, while sulfuric acid (H 2 SO 4 ) and hydrogen peroxide (H 2 O 2 ) were used as the leachants for chemical ...

Metal leaching ef?ciency under various leaching processes The metal leaching ef?ciencies under various leaching processes (at 2% (w/v) pulp density) are shown in Fig. 7. Bioleaching consistently resulted in the highest metal leaching ef?ciency for all metals investigated. This is followed by spent medium leaching which generally attained about 63–93% ef?ciency achievable with bioleaching ...
