Recovery of Secondary Gold

  • J. C. Yannopoulos

Abstract

The cleanest kinds of precious metal scrap are old jewelry, metal parts of old dentures, and the dust and bits produced in the manufacture of jewelry or dentures. Old jewelry may be made of sterling1 silver, carat2 gold (alloyed gold), or of base metals plated with gold. Dentists often use high-quality gold, platinum, or alloys of gold with platinum, silver, and/or copper.
