Biotic factor does not limit operational pH in packed-bed bioreactor for ferrous iron biooxidation
(Oxford University Press, 2012-12-01)
Ferrous ion biooxidation is a process with many promising industrial applications: mainly regeneration of ferric ion as an oxidizing reagent in bioleaching processes and depuration of acid mine drainage. The flooded packedbed ...

Oxygen solubility in copper bioleaching solutions
(Elsevier, 2017-01)
Oxygen is usually the limiting reagent in bio-leaching processes. For this reason, aeration is a key point to take into account when designing such processes, and the oxygen saturation concentration is an important variable ...

Causes of inhibition of bioleaching by Cu are also thermodynamic
(Wiley-Blackwell, 2019-01)
BACKGROUND: Cu is an indispensable natural resource for society, as its use is widespread and essential for many technologies. Consequently, worldwide production is around 18×106 tn year−1, and close to 25% is produced by ...
