Zinc (G12) and lead (G14), then, are both chalcophiles and thus tend to occur in sulfides and other compounds with low-electronegativity nonmetals. But, you say, based on electronic shell structures zinc should have a common oxidation state of +2 while lead, in a different group, should be able to reach +4.

The recovery of the precious metals like gold and silver from the cyanide solution is almost universally accomplished by precipitation with zinc, either in the form of fine threads or of dust (the condensed fume recovered in the process of retorting the metal).. The phenomena of precipitation are essentially electrical and may be traced to the action set up by two metals of …
Gold, silver, lead, zinc, and copper are valuable non-ferrous metals that paved the way for modern civilisation.
