Silver- a soft, white lustrous transition metal that possesses the highest electrical conductivity of any element, most silver is produced as a spin-off of copper, gold, lead, and zinc refining. The metal emerges naturally in its untainted, free form (native silver), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. This long been valued metal is not only used as an accessory, industrially, they are used in electrical contacts and conductors, in specialized mirrors, window coatings and in catalysis of chemical reactions. The compounds of silver are also used in photographic film and X-rays.
In general, silver is extorted from ore by smelting or by means of modernized technique of chemical leaching. Europeans spotted a vast quantity of silver in the New World in the present Mexican State of Zacatecas (exposed in 1546) and Potosi (Bolivia, also discovered in 1546), which activated an period of price increases in Europe.
