چکیده انگلیسی
The purpose of this study was to test the feasibility of using iron and sulphur oxidizing bacteria for the acid leaching of a high grade Pb–Zn ore material. Three strains (ATCC 13661, NCIMB 13537 and C2-TF) of Acidithiobacillus ferrooxidans and two strains (MT-TH1 and MT-13) of Sulfobacillus thermosulfidooxidans were tested in this study. The bioleaching was monitored by measuring the dissolved metals and by X-ray diffraction analysis of leach residues. The bioleaching efficiency varied between 0.014 and 0.35. The maximum dissolution of lead was achieved with the mesophilic At. ferrooxidans (NCIMB 13537) at 30 °C. The maximum recovery of zinc was achieved with moderately thermopilic S. thermosulfidooxidans (MT-TH1) at 45 °C.
