Silver. 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.

If a nonmetallic mineral has a shiny, reflective surface, then it is called "glassy." If it is dull and nonreflective, it is "earthy." Other types of nonmetallic lustres are "silky," "pearly," and "resinous." Lustre is a good diagnostic property, since most minerals will always appear either metallic or nonmetallic.

An ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining ; they are then refined (often via smelting ) to extract the valuable element, or elements.
