Abstract :

<p> The study of bioleaching using anaerobic bacteria and fungi at different physico chemical parameters was estimated using heterotrophic microorganisms. The incubation period, pH, temperature and ore concentration was performed to measure the ions released from the Mn, Cu, Pb & Fe ores during the process of growth of the organism from 24 hours to 144 hours. The results for the order of affinity showed as Pseudomonas aerogens: Cu>Fe>Mn>Pb, E.coli: Cu>Fe>Mn>Pb, Aspergillus niger: Fe>Mn>Cu>Pb and Trichoderma sp.: Mn>Cu>Pb>Fe. The incubation time was found for the bacteria more effective between 72– 96 hours and for the fungal organism as 120 hours. The pH was observed between 7 for bacteria and 5 for fungal organism as maximum for bioleaching</p>
