Kinetics of Fe²⁺ Oxidization at Different Initial Fe²⁺ and Fe³⁺ Concentration in the Presence of Moderate Thermophilic Bacteria

Abstract:

In the bacterial leaching, the oxidation of Fe²⁺ is very important process. According to the results of this paper, Fe²⁺ and Fe³⁺ concentration effect on the growth of moderate thermophile. The optimum conditions for growth of moderate thermophile are the initial concentration of Fe²⁺ at 0.16mol/l. It indicates the existence of the optimum conditions including initial concentrations of Fe²⁺ and Fe³⁺ for the bio-oxidation Fe²⁺. To increase the initial concentration of Fe³⁺ can enhance the oxidation rate of Fe²⁺. The dynamic model of the moderate thermophile oxidation Fe²⁺ has been established by analyzing and calculating test data with the Matlab software.
