Oxidative dissolution of bornite by Acidithiobacillus ferrooxidans
(Elsevier B.V., 2010-01-01)
The oxidation of finely ground (-200 mu m) bornite (Cu(5)FeS(4)) by Acidithiobacillus ferrooxidans was evaluated in oxygen uptake and shake flasks experiments. The oxidation was a net acid-consuming reaction. Residual ...
Oxidation of isochemical FeS2 (marcasite-pyrite) by Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans
(Elsevier B.V., 2007-01-01)
A research-grade mineral sample that contained marcasite and pyrite (FeS2) was subjected to the oxidation by Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans. Oxidation of FeS2 by A. ferrooxidans produced ...
Oxidative dissolution of covellite by Thiobacillus ferrooxidans
(1999-12-01)
Oxidation of research-grade covellite was investigated in respirometric and growth experiments with Thiobacillus ferrooxidans. Covellite was directly oxidized by T. ferrooxidans in respirometric experiments, but the pH of ...

Effect of Na-chloride on the bioleaching of a chalcopyrite concentrate in shake flasks and stirred tank bioreactors
(2013-07-18)
Oxidative dissolution of chalcopyrite at ambient temperatures is generally slow and subject to passivation, posing a major challenge for developing bioleaching applications for this recalcitrant mineral. Chloride is known ...
Estudos físico-químicos e de lixiviação de calcopirita (CuFeS.IND.2) por Acidithiobacillus ferrooxidans
(Universidade Estadual Paulista (Unesp), 2010-06-18)
A mineração é um dos segmentos mais importantes da economia por estar diretamente relacionada à obtenção de metais de base destinados a diversos tipos de indústrias. No entanto, os resíduos da atividade mineralógica tem ...

Mineralogía del proceso de oxidación bacteriana de arsenopirita (FeAsS) y pirita (FeS2)
(2010)
Se realizó la caracterización mineralógica del proceso de oxidación bacteriana de la arsenopirita y pirita, sin adicionar al medio de crecimiento sulfato ferroso o azufre elemental como fuentes principales de energía, ...
New advances in copper biomachining by iron-oxidizing bacteria
(Pergamon-Elsevier Science Ltd, 2016-11)
The machining of copper contained in oxygen-free copper workpieces by extremophile bacteria has been studied. The effect of the main parameters affecting the continuity of the process and which decrease the removal rate ...
