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 ...

Biologically enhanced dissolution of a pyrite-rich black shale concentrate
(1997-01-01)
The acid leaching of a pyrite-rich black shale concentrate (7% S) was tested in this study. The experiments were performed at 5-30% pulp densities and with inoculations of Fe- and S-oxidizing thiobacilli (Thiobacillus ...
