Gold Ore Example

Photos of gold ores, quartz, telluride gold ore and gold

Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent.
