Today’s silver comes from three primary sources: silver mining; silver produced as a by-product of mining for other metals; and silver recycled from used materials, including old jewelry and photographic films and chemicals. Silver market surplus and deficits. Silver is rarely found in its pure form, called native silver.

2. Gold Processing and Extraction and the Role Played by Bacteria. Gold mining can be open-pit or deep shaft mixed with other HM such as copper (Cu), silver (Ag) and lead (Pb). Its location determines the type of mining process to be used in extraction and the amount of wastes that will be generated.
