All that glitters is gold, at least when it comes to the 3,000 tonnes or so of gold mined annually around the world. In addition, around 1,000 tonnes of gold are recycled. The jewellery industry remains the biggest user of this precious metal, while one third of all gold in the world is kept by central banks and an even larger share is in private ownership. The market for precious metals is controlled in large part by these financial operators. However, qualities such as high durability, good conductivity, high temperature resistance and resistance to corrosion mean gold is very much in demand within the electronics, aerospace and pharmaceuticals industries. Mobile telephones and computers are two good examples of where gold is an important metal.
