The main objective of this work was to investigate the dissolution of Fe from Cayeli copper ores, via a bioleaching process using Acidithiobacillus
Effectiveness of sulfur with Acidithiobacillus
and gypsum in chemical attributes of a Brazilian sodic soil.
Comparsion of bioleaching of copper sulphides by Acidithiobacillus
Metal solubilization, applying bacteria Acidithiobacillus
spp is being done for the recovery of copper and uranium by heap, dump and in situ leach techniques on a commercial scale, It is estimated that around 35 % oftotal copper is obtained through bacterial leaching processes.
Para esto, las alternativas planteadas comunmente son la preaireacion, tostacion, oxidacion a alta presion y oxidacion bacteriana con Acidithiobacillus
ferrooxidans y thiooxidans (Rohwerder & Sand, 2003).
2006) also found a reduction of pH of the soil under cowpea bean biofertilizer rock when applied in higher doses, emphasizing the effect of Acidithiobacillus
and sulfur used in the production of biofertilizer, which results in the generation of sulfuric acid and subsequent reduction of the soil pH.
Specifically, the bacterium Acidithiobacillus
ferrooxidans has been identified in ASS (Durr et al.
Bio-decompositionof rock phosphate containing pyrites by Acidithiobacillus
Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus
ferrooxidans--Research on a model system.
Among specific topics are microbial ecology in extreme acidic pit lakes of the Aberian Pyrite Belt in southwestern Spain, galactose as an inducer of the production of extracellular polymeric substances by Acidithiobacillus
ferrooxidans, evidence for widespread dissimilatory hydrogen metabolism among acidophilic bacteria, immobilizing new isolated iron oxidizing bacteria on natural carriers, and the influence of pyrite on the galvanic assisted leaching of chalcocite concentrates.
In case of Acidithiobacillus
thiooxidans, gold (I)-thiosulfate was entered into the cell of A.
The inoculation of the sulfur-oxidizing bacteria Acidithiobacillus
with elemental sulfur generates sulfuric acid, and, different from gypsum application, the H+ released by the acid may contribute decisively to reduce the pH in sodic soils (STAMFORD et al.
