A crucial step in identifying gold vs iron pyrite involves observing their physical properties. Here are some key differences: Color. A mineral's color is a key trait for telling gold from iron pyrite. Gold exhibits a rich, deep yellow hue that is often described as buttery or metallic. This distinctive color is one of the reasons gold has ...

Pyrite is actually iron pyrite is iron sulfide which grows as a crystal. It is possible for microscopic quantities of gold to be trapped in the crystal growth. That process is entirely dependent on the conditions where the pyrite crystals grew. So it is impossible to say how much gold is possible because it depends on where it was mined from.

I use to have a mine in which all of the gold was in pyrite. I would roast the ore using only the heat of a campfire. This drives the sulfur off from the pyrite and turns it into magnetic iron. A magnetic separator would yield a clean pyrite concentrate and I would dissolve the iron with H2SO4. Just A thought. Randy in Gunnison
