Silver: A native element, mineral, alloy, and byproduct
When found, it is often associated with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals. Unlike gold, it is rarely found in significant amounts in placer deposits. Native silver is sometimes found in the oxidized zones above the ores of other metals.

Silver can be found combined with a number of different elements such as sulfur, arsenic, antimony or chlorine to form a variety of minerals and ores, such as argentite, chlorargyrite, and galena. It is also found in very small amounts in gold, lead, zinc and copper ores. Silver is malleable which means it can be hammered into thin sheets.
