Popis: 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.
