Silver Extraction from Zinc [Parkes Process] | Hindustan Zinc

The process takes advantage of two liquid-state properties of Zinc – the First is that Zinc is immiscible with Lead and the Second that Silver is 3000 times more soluble in Zinc than it is in Lead. When Zinc is added to liquid Lead that contains Silver as a contaminant, the Silver preferentially migrates into the Zinc.

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 as ...

How silver is made - material, making, history, used ...

Silver is rarely found alone, but mostly in ores which also contain lead, copper, gold, and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores, the Parkes process is used. In this method, the ore is heated until it becomes molten.
