Electrolytic recovery of gold from aqueous solutions ...

Electrolytic processes for metal winning from dilute solutions were first developed to recover gold and silver from dilute cyanide leach liquors by the Siemensalske process. Use of a vertical sheet cathode in the Siemensalske process is limited to the electrolysis with small current density and low current effic- iency[3 4 18] only.

US4734171A - Electrolytic process for the simultaneous ...

An improved process for recovering gold from gold-containing materials by iodide/iodine leaching is provided wherein the pregnant lixiviant containing solubilized gold and iodine is treated in an electrolytic cell to reduce gold in solution to elemental gold for recovery and reduce iodine to iodide at the cathode so as to prevent iodine from interfering with subsequent gold recovery processes ...

Electrolytic Gold Extraction - Mineral Processing & Metallurgy

Precipitation by means of zinc: 2KAuCN2 + Zn = 2Au + K2ZnCN4. The gold is separated from the solution by either running it over zinc shavings or by means of electrolysis. In either case the gold is deposited as a black mud and is periodically collected and refined.
