Abstract
The main goal of the experiment was to leach minerals using microbes. To accomplish this
goal, the course dealt with the acquisition of adequate bacteria, by taking water samples in the
underground mine “Reiche Zeche”. Later leaching in stirred tank reactors was performed with two
different substrates: synthetic GaAs and indium-bearing sphalerite ore. The leaching experiment
was continuously monitored by the evolution of pH and redox potential. Samples were taken
regularly in order to allow an evaluation of the actual leaching performance.
