The Source of Gold - Its Ores and Minerals

Iron pyrite is an exceedingly common mineral associated with gold, but it also serves as a reducing agent. Therefore whenever gold is found encased in pyrite, it is always present as free gold and not as some type of gold sulphide. Gold is also found at times in chalcopyrite, galena and arsenopyrite and stibnite, but not as a rule in such large amounts as may be found in pyrite. Other minerals ...Iron pyrite is an exceedingly common mineral associated with gold, but it also serves as a reducing agent.
