Bioleaching Refractory Gold

The reactor configuration allows to perform a separate optimization of the rate of oxygen transfer into solution and the rate of solid-fluid mixing. The use of the reactor, allowed an efficient bioleaching of a pyrite gold concentrate at 50 % pulp density. A sample of pyritic gold concentrate was used in the bioleaching experiments.
