    After flotation separation, the concentrate would contain 1.7 percent silver, 10 to 15 percent lead, 10 to 15 percent copper, and 6 percent antimony. Approximately 25 percent of the silver produced comes from ores actually mined for their silver value; the other 75 percent comes from ores that have as their major metal value either lead

    E-waste precious metal refining system is designed to refine and recover precious metals like gold, silver, palladium(Pd) and platinum(Pt) from electronic waste (e-waste) like circuit boards, including CPU, RAM, pins, and other computer components. E-waste is classified as hazardous material therefore should be managed properly. However, the presence of precious metals (PMs) in e-waste such as

  • Liquation Wikipedia

    The copper-lead alloy created can be tapped off and cast into large plano-convex ingots known as ‘liquation cakes’. As the metals cool and solidify the copper and the silver-containing lead separate as they are immiscible with each other. The ratio of lead to copper in these cakes is an important factor for the process to work efficiently.

  • The Silver Extraction Process athens123

    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 contains just a small percentage of

  • Determination of lead as basic lead chromate and its

    Lead is quantitatively precipitated as basic lead chromate, PbO.PbCrO 4, by addition of sufficient potassium chromate, followed by ammonia, to the boiling solution of the lead salt.If a silver salt is also present the silver chromate first formed dissolves in the excess of ammonia.
