Silver can be found in nature both in its native state and combined with sulphur, arsenic, antimony or chlorine in a variety of minerals (e.g., argentite, Ag2S).
Silver deposits are in Canada, Australia and the United States but the maximum production in the last two centuries was reached in the mine of Guanajuato, Mexico. Since 2006 Peru is the biggest producer of silver in the world with over 111.6 million ounces of silver produced.
Apart from minerals, silver is also obtained from the electrolytic refining of copper. The commercial grade of silver is 99.9% pure. There are degrees of purity up to 99.999%.
