• 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 of Galenite is silver-bearing and is known as Argentiferous Galenite (formula (Pb.Ag)S ) and the lead obtained from this ore

  • Galena Lead Ore Processing frjigmachine

    Galena Lead Ore Processing. Galena is kind of lead mineral with big density 7.4-7.6g/cm3 and gangue density of 2.2-3g/cm3. Its big embedded granule and density difference makes gravity a great beneficiation method to gain high grade galena concentrate. For gravity separation of galena, the separator involved is mainly jigger.

    Galena is the main ore of lead, used since ancient times. Because of its somewhat low melting point, it was easy to liberate by smelting. It typically forms in low-temperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue. In these deposits significant amounts of silver occur as included silver sulfide mineral phases or as limited silver in solid solutionwithin the galena structure. These argentiferous galenas have long b
