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.

Zinc mining Wikipedia
Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining.A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such

Recovery of Gold by Precipitation with Zinc
The recovery of the precious metals like gold and silver from the cyanide solution is almost universally accomplished by precipitation with zinc, either in the form of fine threads or of dust (the condensed fume recovered in the process of retorting the metal).. The phenomena of precipitation are essentially electrical and may be traced to the action set up by two metals of different
