History of Silver Mining

Silver has been known since ancient times. It is mentioned in the Book of Genesis, and slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BCE. Genesis (Greek: Γένεσις, having the meanings of birth, creation, cause, beginning, source and origin) is the first book of the Torah (five books of Moses) and hence the first book of the Tanakh, part of the Hebrew Bible; it is also the first book of the Christian Old Testament. ...

Europeans found a huge amount of silver in the New World in the now Mexican States of Zacatecas and San Luis Potosí, which triggered a period of inflation in Europe. The conquistador Francisco Pizarro was said to have resorted to having his horses shod with silver horseshoes due to the metal's abundance, in contrast to the relative lack of iron in Peru. Silver, which was extremely valuable in China, became a global commodity, contributing to the rise of the Spanish Empire. The rise and fall of its value affected the world market.

Silver mining was a driving force in the settlement of western North America, with major booms for silver and associated minerals (lead, mostly) in the galena ore silver is most commonly found in. Notable silver rushes were in Colorado, Nevada, Cobalt, Ontario, California and the Kootenay region of British Columbia, notably in the Boundary and "Silvery" Slocan. The largest silver ore deposits in the United States were discovered at the Comstock Lode in Virginia City, Nevada, in 1859. A Silver rush is the silver-mining equivalent of a gold rush. ...

Areas of silver mining

Silver is found in native form, combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag2S) and horn silver (AgCl). The principal sources of silver are copper, copper-nickel, gold, lead and lead-zinc ores obtained from Canada, Cobalt, Ontario, Mexico (historically Batopilas), Peru, Australia and the United States.

This metal is also produced during the electrolytic refining of copper and by application of the Parkes process on lead metal obtained from lead ores that contain small amounts of silver. Commercial grade fine silver is at least 99.9 percent pure silver and purities greater than 99.999 percent are available. Mexico is the world's second largest silver producer after Peru in 2005. According to the Secretary of Economics of Mexico, it produced 80,120,000 troy ounces (2492 metric tons) in 2000, about 15 percent of the annual production of the world.
