Depletion gilding relies on the fact that gold is highly resistant to oxidation or corrosion by most common chemicals, whereas many other metals are not. Depletion gilding is most often used to treat alloys of gold with copper or silver. Unlike gold, both copper and silver readily react with a variety of chemicals.

[2] For the year 2007, gold output rose 12% from 2006 to 276 tonnes (9,700,000 oz; 304 short tons) to become the world's largest for the first time—overtaking South Africa, which produced 272 tonnes (9,600,000 oz; 300 short tons ...
