possible to achieve a gold recovery of 99 % after one hour of leaching for mechanically activated sample. In Tables 2-3 are shown redox potentials under different times of electrolysis. From Table 3 it is evident that maximum recovery of gold in 15 minutes was 99.79 % at the redox potential 500-523 mV. The results have
Gold - The electrolytic gold recovery process employs hydrochloric acid as an electrolyte, a thin sheet of gold with more than 99.5% purity as a cathode, and a gold alloy anode. Following the ion transfer, high purity gold is transferred onto the cathode. This process is known as the Wohlwill process.
