Step leaching technique with a low starting pulp density was found to be most efficient to obtain good leaching rates at high pulp densities. The cyanidation results of the biotreated samples at 10% pulp density continuous run showed about 85% gold recovery and 98% silver recovery, as against 38% and 63% obtained prior to treatment.
