According to the US Geological Survey, about 2593 tons (about 83.4 million ounces) of gold are produced from various minerals around the world. In addition, about 943 tons of recycled gold come from precious metal scrap and used electronic products, as well as from jewelry And dental alloys scrap gold alloy recovery.
