Bioleaching of non-ferrous sulfides with adapted thiophillic bacteria

Bioleaching of Pyrrhotite with Bacterial Adaptation and Biological Oxidation for Iron Recovery

“…Moreover, in the third and fourth adaptations, the pH showed an equilibrium constant after 15 days of inoculation, which indicates that the optimum adaptation of A. ferrooxidans was reached by day 15. Previous studies have reported optimum adaptation periods of one week [25,26], two weeks [27][28][29], and four weeks [30,31]. Reference [20] also mentioned that the repetition of adaptation performance leads to a reduction in the lag phase of bacteria and improved biological oxidation capacity of bacteria.…”
