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.

Silver mining - Wikipedia

Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), and galena (a lead ore often containing significant amounts of silver). As silver is often found in conjunction with these or alloyed with other metals ...
