Where does all the gold in the world come from?

About 1500 tonnes of gold are mined each year. About two-thirds of this comes from South Africa and most of the rest from Russia. Seawater contains about 4 grams of gold in 1,000,000 tonnes of water. Overall this is a huge amount of gold stored in the oceans but, because the concentration is so low, attempts to reclaim this gold have always failed.
