The Silver Extraction Process - athens123

2018-1-17  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 ...

Silver processing - The metal and its alloys Britannica

2020-8-15  Silver processing - Silver processing - The metal and its alloys: Even silver that has been fully work-hardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.

Silver Gold Recovery Flotation Process

2021-2-19  The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class ...

Investigation of silver extraction from a silver-sulphur ...

A thiourea leach extracted only 24% of the silver, partly because silver re-precipitation occurred. It was evident that some form of pretreatment was needed to make the silver amenable to leaching. Pressure oxidation with sulphuric acid at 200°C dissolved 56% of the silver in 4 h provided an initial acid strength of 90 g/L was used.
