Gold is a dense, soft, shiny, malleable, and ductile metal. It is a chemical element with the symbol Au and atomic number 79 with a symbol of Au. Gold is the most malleable and ductile of all the metals, and it is important to consider that gold is rather scarce.It's quite hard to find and extract in large quantities with pre-industrial technology.
Gold is usually alloyed in jewellery to give it more strength, and the term carat describes the amount of gold present (24 carats is pure gold). It is estimated that all the gold in the world, so far refined, could be placed in a single cube 60 ft. on a side. The most common gold compounds are auric chloride (AuCl 3) and chlorauric acid (HAuCl

Other gold minerals occurring in ore-forming environments ( Table 3) include both alloys and intermetallic compounds (with defined stoichiometries) that form where other metals are also concentrated, such as the PGE (porpezite and rhodite), copper (auricupride), bismuth (maldonite), and antimony (aurostibite).
However, gold is readily dissolved in a number of solvents, including oxidizing solutions of hydrochloric acid and dilute solutions of sodium cyanide. Gold readily dissolves in these solvents because of the formation of complex ions that are very stable.

To know what type of rock is gold associated with you must see that the minerals most common in placer deposits are platinum, iridosmine, magnetite, iron pyrites, ilmenite, zircon, garnets, rutile and barytes; wolfram, scheelite, brookite and diamonds are less common. Diamonds are associated with gold in Brazil, and also occasionally in the Urals and in the United States. In auriferous quartz
Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), which forms a soluble tetrachloroaurate anion.
