Silver has medical uses such as an ingredient in antibiotics and dental fillings. Also, when silver is used in clothing it can prevent bacterial and fungal infection and minimize odor. It has the highest electrical conductivity of any metal but has not replaced copper because of it's higher cost. Silver is also used for cutlery, jewellery and money.

Most silver is extracted from silver ores but most are mined from Native Silver. Silver can be found pure but is usually mixed with gold, arsenic and antimoney. Silver occurs naturally as an alloy in minerals such as argentite and chlorargyrite. Silver is mined through a series of mines known as an open cut mine, a shaft mine and a panning. It is extracted by either the Moebius process, the Balbach-Thum process or the Parkers process.

As of February 19, 2010 silver costs $16.37/oz and $2.63 for a 5 gram bar.

P.S- Sorry Mr Graves I could not figure out to place a picture (I'm not good with computers).
