The Silver Extraction Process athens123

The Silver Extraction Process. 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

Silver processing Britannica

Silver is removed by the Parkes process, which consists of adding zinc to the molten lead bullion. Zinc reacts rapidly and completely with gold and silver, forming very insoluble compounds that float to the top of the bullion. These are skimmed off and their zinc content recovered by vacuum retorting.

Silver processing The metal and its alloys Britannica

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.

Common Questions About Silver Extraction Process (II)-xinhai

The process of extracting silver by the fuming method is complicated, high in cost and low in recovery rate. Therefore, the silver extraction process should concentrate silver in lead and copper concentrate to the greatest extent. In general, the recovery rate of lead-zinc-copper associated silver ore is lower than that of silver-gold ore
