Silver mining Wikipedia

Once silver ore has been removed from a mine, it is crushed into a fine powder. Silver is commonly extracted from the powdered ore by smelting or chemical leaching. Silver's melting point occurs at 962 C (1764 F, 1,235.15K). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes. Ore treatment by mercury amalgamation, such as in the patio process or pan amalgamation was widely used through the 1800s, but is seldom used today.
