The majority of silver is produced as a by-product of mining other metals such as copper and gold. The physical properties of silver include high ductility, electrical conductivity, malleability, and reflectivity. Silver has widespread uses throughout the global economy, from jewelry to cell phones to surgical tools.Strong and malleable, silver can take various forms. It is one of the best thermal conduits and has the highest electrical conductivity of all other metals including copper. These characteristics make silver a perfect component for many of today's modern electronics.
In 2014, the estimated uses for silver were electrical and electronics, 42%; coins and medals, 35%; photography, 13%; jewelry and silverware, 7%; and other, 3%. Other applications for silver include use in bandages and pharmaceuticals for wound care, batteries, bearings, brazing and soldering, catalytic converters in automobiles, cell phone covers to reduce the spread of bacteria, clothing to minimize odor, electroplating, inks, mirrors, solar cells, water purification, and wood treatment. An emerging use of silver is in athletic clothing where biosensing silver fibers may be woven directly into the fabric. This athletic clothing transmits biometric data such as the wearer’s real - time heartbeat to a sensor that displays the data. Silver metal in fine powder form is also being used in 3D printing to make jewelry and various other items. Silver was used for miniature antennas in radio frequency identification devices that were used in casino chips, toll road transponders, gasoline speed purchase devices, passports, and on packages to keep track of inventory shipments.
Worldwide silver production increased during 2014 despite reduced demand for the metal across several industries. Specifically, the US Geological Survey (USGS) states in its most recent report on silver that mine output rose to 26,100 metric tons (MT) last year. Global silver mine output is split between primary producers and secondary producers who generate silver as a by product.

1. Cannington Mine
The Cannington Silver and Lead Mine is an Australian underground mine located in north-west Queensland, in the Shire of McKinlay, about 200 kilometres (124 mi) southeast of Mount Isa. The deposit was discovered by Broken Hill Proprietary Company (BHP) in 1990. Although sitework and underground mining began in 1997, full production was not achieved until early 1999, with 1.5 million tons of ore processed in 1999. Production since has reached 3 million tons of ore per year. As of 2010 it was the largest and lowest cost silver and lead mine in the world. The expected life of the Cannington mine is 25 years.
