Abstract: Recovery of copper from personal computer boards was evaluated by means of microbial leaching. Copper leaching was performed in two stages. In the first stage, the bacteria were grown in a culture medium and in the second stage; Copper containing boards were added to the metabolites produced by the bacteria. Bioleaching was performed using autotrophic bacteria A. thiooxidans and A. ferrooxidans and a mixed media of them. Highestcopper recovery (91%) is achieved in S / L ratio of 5gr / Land in the mix media containing both A. thiooxidans and A. ferrooxidansbacteria.
