Silver Mining and Refining Education

Silver is extracted from lead ores in large furnaces, a process called cupellation. Most silver is extracted from ores with a froth flotation process, which was discovered early in the 20 th century. In this process, crushed ore is placed in a bath.

Silver element extraction methods Open pit, underground

The ore containing silver needs to be refined to obtain pure silver as an end product. The silver precipitate obtained previously may contain some impurities and so the impure silver is purified by the electrolytic method. The process requires a block of impure metal to be the anode while a thin strip of pure silver is fetched as cathode.

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.
