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 o C (1764 o F, 1,235.15K). As such, industrial metallurgic processes are needed to prepare silver for commercial purposes.

Lead processing Britannica

Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of the silver content often exceeds that of the lead, in which case it is deemed a silver ore. Other commercially significant lead-containing minerals are cerussite (lead carbonate) and anglesite (lead sulfate). These are known as secondary minerals in that they derive from galena through natural
