Coming from Engineering cum Human Resource Development background, has over 10 years experience in content developmet and management. This article explains about those features and identification methods in detail. It is also known as fool’s gold since resembles gold. Both of these minerals have their unique commercial uses in many ways. There are very simple ways to distinguish gold from Pyrite. There are distinct differences between gold and pyrite that are discernable with the human eye. Gold vs Pyrite Summary. "Fool's gold" is a common nickname for pyrite. Nevertheless, closer observation reveals that they do not have similar colours. Pyrite shatters and crumbles if dealt a hard blow. I’ve had a lot of people ask questions about various pyrites, you know, I’ve been showing you this one, this Chalcopyrite gold ore piece. Pyrite or iron pyrite is also used to name Iron sulphide. Some of the differences are in their: Density; Color; Hardness; At first glance, spotting the differences between gold and pyrite can be challenging. Therefore, when panning out the minerals, gold will settle down in the bottom of the pan while Pyrite will move freely on the top of the pan. Gold possesses shiny gold colour while Pyrite possesses a brass like yellowish colour. The main difference between gold and pyrite is that gold is a chemical element having the symbol Au whereas pyrite is a mineral having the chemical formula FeS2. La pyrite et l'or sont deux minéraux naturels différents qui ont une coloration presque similaire en apparence. Filed Under: Chemistry Tagged With: Au, Aurum, FeS2, Fool's gold, Gold, gold definition, Iron sulphide, pyrite, pyrite and gold, pyrite definition. Gold has one s-electron outside completed d-shell. Pyrite has the advantage here; it's a bit harder and comes in at 6 to 6.5 on the Mohs' scale. Pyrite and gold are two different naturally occurring minerals that have nearly similar colouration in appearance. How you can tell the difference. The most distinct difference between gold and pyrite is in their hardness. Pyrite is, usually, present in igneous, metamorphic and sedimentary rocks all over the world. • Gold does not react with water, moisture or other corrosive reagents. It is the first simple method of distinguishing one from another. Most of the people used to confuse pyrite as gold due to this reason. 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 brigh… It is a transition metal (electronic structure: [Xe] 4f14 5d10 6s1) in the periodic table. Therefore, there are different methods to differentiate gold from Pyrite. Gold is malleable, unlike pyrite which is brittle. Most all of the chemical and physical properties are different from one another. It is one of the most expensive metals in the world. You consent to our cookies if you continue to use our website. In early days, this had been used to make fire by striking against metal or any other hard material. However, when you do the same movement for a Pyrite sample, it flashes in the presence of light. • Gold shines in any angle even without light, but Pyrite glistens when its surfaces catch the light. As elements go, it's rather soft so a gold nugget can easily be scratched with a pocket knife. C) Shape: Pyrite is usually found as angular pieces, and many of them exhibit the faces of a cube, octahedron or pyritohedron. If you move your gold pan in a circular motion in the sunlight, gold will maintain a consistent color, while pyrite will flash in the sunlight. Gold has a golden to yellow color. You can understand why it's called "fool's gold.". When you move a gold in a circular motion, it maintains a consistent colour along every movement. Gold is made of gold atoms whereas Pyrite consists of Ferrous and Sulfur molecules. Gold and pyrite may seem similar because of their appearance, but the reality couldn’t be further from the truth. Most native gold is alloyed with silver, and if the silver content is high enough, the specimen will have a whitish yellow color. Terms of Use and Privacy Policy: Legal. It has the cubic close-packed crystal structure. It has a yellowish colour when in mass, but black, ruby or purple in colour when is divided into fine particles. It is very valuable due to its lustrous yellow appearance and many other properties such as malleability. Also, read: Difference Between Coal and Gold. The mineral pyrite , or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Although they look similar, gold and pyrite are very distinct substances.

After you've gained some experience with gold panning and prospecting, you should easily be able to tell the difference between pyrite and real gold simply by looking at its color. Gold only ranks at 2.5 to 3. • Specific gravity of gold is greater than that of Pyrite (Pyrite = 4.95–5.10). Aurum (Au-79 gmol-1) is the chemical name for gold; it is a Latin word. Gold possesses shiny gold colour while Pyrite possesses a brass like yellowish colour. Gold, on the other hand, tends to bend rather than break. Main Difference – Gold vs Pyrite. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. There is a notable difference in their shine too. • Gold and Pyrite can be seen together in the same ore because both of them are formed under similar environmental conditions. Gold is a chemical element in the periodic table. Pyrite is noticeably harder with … Nevertheless, closer observation reveals that they do not have similar colours. • Gold is a pure metal. • Gold is a malleable and ductile structural metal. Nevertheless, Pyrite reacts with many of the chemical reagents. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } • Gold is mostly used in jewelry. With a little practice, there are many easy tests that anyone can use to quickly tell the difference between pyrite and gold. Pyrite received that nickname because it is worth virtually nothing, but has an appearance that "fools" people into believing that it is gold. It has shiny surfaces that catch the reflection of the sun. B) Color: Pyrite has a brassy color. In other words, gold is denser than Pyrite (Gold- 19.30 g•cm−3; at 0 °C, 101.325 kPa, Pyrite- 4.8–5.0 g/cm3). And I have some iron pyrite floating around here. • Gold occurs mainly as grains of metal disseminated in quartz veins. Gold is one of the most malleable and ductile metals on earth. Gold is not present in every part of the world; its abundance is very low. It is a naturally occurring mineral; it is the most abundant Sulphide mineral on the earth.
