  • The Silver Extraction Process athens123

    The Silver Extraction Process The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead The local variety ofsilver processing, preparation of the ore for use in various products Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygenThe lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000silver processing | Britannicasilver, as is described in classical, medieval and renaissance sources on pyrometalurgy The lead reduction smelting process involves twosteps: a fusion of the ore material with lead in a carbonrich environment, followed by the separation of silver from the lead in an oxygenrich environment PeriodSMELTING SILVER rocks4brains
