chemistry of silver mining

Silverore is mined through both open-pit and underground methods. The open-pit method involves using heavymachinerytominedeposits relatively near the earth’s surface. Today’ssilvercomes from three primary sources:silver mining;silverproduced as a by-product ofminingfor other metals; andsilverrecycled from used materials, including old jewelry and photographic films andchemicals.
