Gold is usually associated with Pyrite and other sulfides, and sometimes may not be noticed because of the association with these resembling minerals. In certain localities, minerals that contain these sulfides are heated high enough for the sulfides to dissolve, enabling the Gold to remain intact on the matrix. Such Gold is known as quot;Roasted

Gold Mineral Properties  Geology3

Gold Mineral Properties Geology

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties some of which are unique to gold. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.

In fact only a few rare tellurides are found without gold. A few of the tellurides are nagyagite, calaverite, sylvanite and krennerite. These are all minor ores of gold and their contributions to the supply of gold pales next to native gold's own contribution. Occasionally these minerals are associated with native gold.

Geochemistry of hydrothermal gold deposits A review

Because gold and Asbearing minerals (pyrite and arsenopyrite) correlate positively, As is considered to play an important role in the concentration of Au in hydrothermal systems. When the S content is extremely low, native As would form, such as the case in the Baogutu gold deposit, where native As is the predominant gold carrier .
