Gold may be associated with PGE's and chalcophilic elements (Fe, Ni, Cu) that form at the base of magma bodies due to immiscible liquid separation resulting from sulphur oversaturated melts that precipitate out as droplets as temperature decreases, bonding with these elements and settling out due to their high specific gravity (4.5) to coalesce at the base of the melt. It can also be deposited in cracks and fissures by the action of hot ground water. Gold (as well as other elements) in tiny particles is carried in the hot water through the fissures building up into the deposits we find today. A good reference to the genesis of gold can be found in Gold by R.W. Boyle; published by Van Nostrand Reinhold New York.

Gold is a very unreactive element, so it occurs as gold metal in nature. However, aluminum is more reactive, and so it occurs in aluminum ore (aluminum oxide) in nature, not as aluminum metal.
What are the raw materials for gold?
If the gold is placer gold - the kind at the bottom of streams that the old prospectors used to dredge out of the sand - it's usable gold when you get it. If it's gold that has to be mined, then you need gold ore, a cyanide (either sodium, potassium or calcium can be used), some sodium hydroxide, a little lead nitrate...this is a very nasty process and it's illegal in a lot of places.
