The Silver Extraction Process - athens123
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
Silver mining - Wikipedia
Silver mining is the extraction of the precious metal silver from the Earth through excavation (i.e., mining). Silver is found in a native form very rarely as nuggets in placer deposits and veins. It is more commonly combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag2S), chlorargyrite ("horn silver," AgCl)…
Silver Gold Recovery Flotation Process
17-10-2016· The discharge from the tube mill is first passed through a 4-mesh screen to separate out coarse material, which is laundered direct to the classifier. The remainder of the pulp, diluted to give a W/S ratio of 1/1, passes to a Denver “ Sub-A” Flotation Cell, from which 60% of the gold and silver in the feed is removed as a concentrate.
