Zone Refining. Zone refining is a special method we use to purify metals. It was the invention of William Pfann. It purifies metals to a very high degree. A rod of impure metal is placed in a container which we fill with inert gas. Then we place a circular heater around the rod at the top.

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 ...

In the next few blog entries, we'll review both the refining and ballistic properties of silver bullets to see if they live up to the legend. The concept of silver bullets gained traction after the events of the 1760s in Gévaudan, France. During that time, the Beast of Gévaudan attacked and killed multiple people living in or near the town.

The Parkes zinc-desilvering process is the most widely used pyrometallurgical method of refining lead bullion. As in smelting, the lead is first melted and again allowed to cool below the freezing point of copper, which crystallizes and, along with any remaining nickel, cobalt, and zinc, is removed by skimming.

Finally, the molten lead is refined. Pyrometallurgical methods are usually used to remove the remaining non-lead components of the mixture, for example the Betterton-Kroll process and the Betts electrolytic process. The non-lead metals are usually sold to other metal processing plants. The refined lead may be made into alloys or directly cast. [1]

One ancient process for extracting the silver from lead was cupellation. Lead was melted in a ash 'test' or 'cupel' and air blown across the surface. This oxidised the lead to litharge, and also oxidised other base metals present, the silver (and gold if present) remaining unoxidised. [1]

Silver is often extracted by constant smelting, but electrolytic refining is becoming more popular in the modern era. An electric current forces the silver ore to separate from copper, lead, and zinc, producing many types of metals all at once. With modern technology, the electrolytic method is much faster and cheaper than using smelters or ...
