Pyrite and gold relationship

What does Gold Look Like in Nature? Identify Real Gold

pyrite and gold relationship

Gold and pyrite are very different minerals, but because of their similar color they are often confused by beginners gold panning for the first time. Prospectors will. Pyrite, or what's commonly known as "fool's gold," has tricked countless prospectors into thinking they've found valuable gold when they really didn't. Ever since. () indicated that the relationship of gold and arsenic in pyrite (CAu=CAs +4×) puts an upper limit on the solubility of gold in pyrite;.

Even individuals without any past experience will likely see a noticeable difference between the two minerals when they're placed side-by-side.

Pyrite has a darker yellow color to it that's similar to brass, while gold has a vibrant yellow color that's highly reflective to the surrounding light. Holding a piece of gold under the light will reveal a bright yellow color that's stronger than the dull yellow color of pyrite. Until you're able to easily identify gold, you should keep a piece of pyrite around in your pocket to compare your finds with.

Shape The shape of pyrite nuggets is something that's quite unique and not found with traditional gold. Nearly all pieces of pyrite are formed into the shape of crystals, some of which may have nearly half a dozen pylons coming off the base.

Of course this may be hard to see in smaller pieces of pyrite, as the crystals will be small and hidden as well. Gold, on the other hand, is never formed as crystals, but instead it's formed as nuggets and small flakes with little-to-no symmetry.

Difference Between Pyrite and Real Gold

Weight You probably know by now that gold is one of the heavier naturally-occurring metals found. The structure, color, hardness and specific gravities are all indicators that will help to differential between the two.

The most obvious way to tell the difference between them is the specific gravity. When panning out material, gold will settle and concentrate in the bottom of the pan, but pyrite will move freely in the pan.

You will often see them at the surface mixed in with the lighter sands and gravels.

Proper gold panning will easily separate the two, as the small specks of pyrite will wash out of the pan while the denser gold particles will be retained. The color is also a good indicator between the two.

Difference Between Pyrite and Real Gold

While gold obviously has a golden color, pyrite generally has a brassy and shiny coloration. It has shiny surfaces that catch the reflection of the sun.

The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, and the sulfosalts. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Pyrite is so named from the Greek word for fire pyr because it can create sparks for starting a fire when struck against metal or stone.

This property made it useful for firearms at one time but this application is now obsolete. Pyrite was once a source of sulfur and sulfuric acid, but today most sulfur is obtained as a byproduct of natural gas and crude oil processing. Today pyrite is sometimes sold as a novelty item or costume jewelry.

Gold can even occur as inclusions inside pyrite, sometimes in mineable quantities depending on how effectively the gold can be recovered. Pyrite has long been investigated for its semiconductor properties. Learn about studies underway to develop pyrite as a material to make solar cells.
