How to Turn Lead Into Gold - ThoughtCo

Sep 22, 2019  While it may never be commonplace to transmute lead into gold, it is practical to obtain gold from lead ores. The minerals galena (lead sulfide, PbS), cerussite (lead carbonate, PbCO 3), and anglesite (lead sulfate, PbSO 4) often contain zinc, gold, silver, and other metals.Once the ore has been pulverized, chemical techniques are sufficient to separate the gold from the lead.

Gold corrosion

Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Yet this is precisely what Russian commercial precious metal trading company, International Reserve Payment System, discovered on thousands of (allegedly) 999 gold coins "St George" issued by the Central Russian Bank ( reference ).

Gold - Wikipedia

Gold does not react with sulfur directly, but gold(III) sulfide can be made by passing hydrogen sulfide through a dilute solution of gold(III) chloride or chlorauric acid. Gold readily dissolves in mercury at room temperature to form an amalgam , and forms alloys with many other metals at higher temperatures.
