It is widely distributed and is almost always associated with quartz or pyrite. It occurs in veins and alluvial deposits, and is often separated from rocks and other minerals by sluicing and panning operations. The metal is recovered from its ores by cyaniding, amalgamating and smelting processes, while refining is carried out by electrolysis.

Gold in its pure state is considered the most beautiful and hence most valuable of the pure metals. It is metallic, having a yellow colour when in mass, though when finely divided it may be black, ruby or purple.

Gold is soft, ductile and the most malleable of metals, and because of this is usually alloyed to give improved strength and durability. Gold’s reflectivity of ultraviolet and visual light rays is low, however it has high reflectivity of infrared and red wavelengths.

Gold is a good conductor of heat and electricity, and is unaffected by air, nitric, hydrochloric, or sulphuric acid and most other reagents. A mixture of one part nitric acid with three parts hydrochloric acid, called aqua regia, dissolves gold. It is also dissolved by solutions of azoimide. Further, it is attacked by sodium, and potassium cyanide plus oxygen.

The most common gold compounds are auric chloride (AuCl3) and chlorauric acid   (HAuCl4).
