Mine production of gold worldwide
China, Australia, Russia, and the United States are some of the largest producers of gold in the world. Global production of gold reached approximately 3,150 metric tons in 2017. Production in China has increased from 320 metric tons in 2009 to an estimated 440 metric tons in 2017. However, large-scale gold production is minimal with only one mine exceeding 300,000 ounces of gold, the Zijinshan gold-copper mine in the Fujan Province. The production value of gold in the United States has increased from 4.9 billion U.S. dollars in 2006 to eight billion U.S. dollars in 2015. One of the largest gold companies in the world, AngloGold Ashanti, is headquartered in Johannesburg, South Africa and was founded in 2004. It generated revenues of 4.3 billion U.S. dollars in 2016. It produced over 3.6 million ounces of gold in 2016, with over half of it being produced in Africa. Most gold mining is performed by large corporations around the world. However, there are smaller independent operations and in some cases, illegal mines have also been formed such as one in the Ashanti Region in Ghana where 18 people were killed in November 2009.
