Enumeration of Acidithiobacillus ferrooxidans adhered to agglomerated ores in bioleaching processes
(2002)
In bioleaching processes, bacteria adhered to agglomerated ores are frequently determined in the washing solution after treating the mineral with different techniques like sonification or chemical treatment with SDS, Tween ...
Solubilization profiles of metal ions from bioleaching of sewage sludge as a function of pH
(Kluwer Academic Publ, 2002-04-01)
Two patterns of solubilization of metal ions resulting from bioleaching of sewage sludge by sulphur-oxidizing Thiobacillus spp. were established as a function of pH. Chromium and copper ions required a pH of 2-3 to initiate ...

Formation of hydrocarbon gaseous compounds during bioleaching of copper sulphide minerals with mesophilic microorganisms
(ELSEVIER, 2008-11)
An experimental study was conducted for assessing the formation of hydrocarbon gaseous compounds during bioleaching of copper sulphide ores with mesophilic microorganisms. Three different mineral samples were used: a pyrite ...

In situ recovery of copper sulfide ores: alternative process schemes for bioleaching application
(Elsevier, 2020)
There is a growing interest in exploring the application of bioleaching for treating copper sulfide ores of decreasing grade and located at larger depth by in situ recovery (ISR) for its potential savings in ore extraction, ...
Nickel recycling through bioleaching of a Ni/Al2O3 commercial catalyst
(Elsevier B.V., 2020-08-01)
Bioleaching studies were carried out on a commercial nickel-based reforming catalyst using two acidophilic bacteria (Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans) under several types of bioleaching mode ...
