<P> Silver 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 . </P> <P> The principal sources of silver are copper, copper - nickel, gold, lead, and lead - zinc ores obtained from Canada, Mexico, Poland, Peru, Bolivia, Australia and the United States . </P> <P> Mexico was the world's largest silver producer in 2014, producing 5,000 metric tons (161 million troy ounces), 18.7 percent of the 26,800 tonne (862 million troy ounce) production of the world . </P> <Table> Top 6 Production Stage Silver Mines <Tr> <Th> Mine </Th> <Th> Country </Th> <Th> 2010 Production </Th> </Tr> <Tr> <Td> Cannington Silver / Lead / Zinc Mine </Td> <Td> Australia </Td> <Td> 38.6 Moz </Td> </Tr> <Tr> <Td> Fresnillo Silver Mine </Td> <Td> Mexico </Td> <Td> 38.6 Moz </Td> </Tr> <Tr> <Td> San Cristobal Polymetallic Mine </Td> <Td> Bolivia </Td> <Td> 19.4 Moz </Td> </Tr> <Tr> <Td> Antamina Copper / Zinc Mine </Td> <Td> Peru </Td> <Td> 14.9 Moz </Td> </Tr> <Tr> <Td> Rudna Copper Mine </Td> <Td> Poland </Td> <Td> 14.9 Moz </Td> </Tr> <Tr> <Td> Peñasquito Polymetallic Mine </Td> <Td> Mexico </Td> <Td> 13.9 Moz </Td> </Tr> </Table>
