Global production of gold mines 2005-2020. In 2005 some 2470 metric tons of gold was produced worldwide. Since then gold production has increased steadily to an estimated 3200 metric tons in ...
Gold production in the United States prior to 1848 was less than 2 metric tons annually. Discovery of gold in Califor nia in that year led to annual production of 60-100 metric Publication approved by the Director U.S. Geological Survey April 26 1988. tons during the 1850's. Gold production gradually declined
Each year global gold mining adds approximately 2500-3000 tonnes to the overall above-ground stock of gold. While gold production has shown an upward trend in recent years this is likely to level off in coming years. Accurately estimating the amount of gold still within the ground is no easy task and this estimate may change in response to several factors such as:
Production from Zarshuran in the Iranian city of Takab in West Azarbaijan began in November 2014 with the inauguration of a facility capable of processing 3 metric tons of gold on top of 2.5 tons of silver and one ton of mercury per year. According to the Mehr news agency the plant is undergoing expansion which will double output by 2017.
About 244000 metric tons of gold has been discovered to date (187000 metric tons historically produced plus current underground reserves of 57000 metric tons). Most of that gold has come from just three countries: China Australia and South Africa. The United States ranked fourth in gold production in 2016.All of the gold discovered thus far would fit in a cube that is
