Silver | Mining in South America

It is a metallic chemical element with the chemical symbol Ag and atomic number 47. The metal exists naturally in its pure, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. A great amount of silver is produced as a by-product of copper, gold, lead, and zinc refining.
