The mineral pyrite, or iron pyrite, also known as fool’s gold, is an iron sulfide with the chemical formula FeS2 (iron(II) disulfide).
The mineral pyrite, or iron pyrite, also known as fool’s gold, is an iron sulfide with the chemical formula FeS?. Pyrite is the most abundant sulfide mineral.
Pyrite’s metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool’s gold. Wikipedia
Pyrite is a brassy-colored mineral featuring a metallic luster resembling gold….Pyrite Geological Properties.
Pyrite has the chemical formula FeS2, meaning it is made up of one iron molecule, Fe, and two sulphur molecules, S. These then combine to form the cubic structure. This is a single pyrite crystal which you can see forms a perfect cube.
Pyrite can be found in soils and sediments throughout the Earth as myriads of microscopic crystals. This pyrite is formed by bacteria that remove oxygen from sulfate in the water, producing sulfide that reacts with iron to form pyrite. More than 90 percent of the pyrite on Earth is formed by microbiological processes.
In this respect, we recognize five types of pyrite provinces: Cyprus, Urals, Lesser Caucasus, Rudnyy Altay, and Filizchay.

How do you distinguish gold from pyrite
Pour some white vinegar into a crystal glass. Pour enough to definitely cover the sample you are testing.
Place the sample in a cup of white vinegar.
Then we rate our song.
Remove the sample and rinse additionally with water.
Why is pyrite called ‘Fool’s gold’
Pyrite is called “fool’s gold” because it looks beautiful to the untrained eye. While pyrite is coppery yellow and has an aluminum luster similar to gold, pyrite can be brittle and more susceptible to breakage than bends like gold. Gold leaves a yellow streak, pyrite has a brown-black surface.
How do I tell gold from pyrite
• Gold has a golden color, but pyrite also has a smooth brass color. • Gold shines from any angle in the absence of light, while pyrite shines when its surface absorbs mass. When you move the gold in a circular motion, it keeps one constant color with each motion.

Is gold pyrite worth anything
It may become useless as a currency, but that doesn’t mean Pyrite doesn’t care – or at least has the potential to keep it. Over the past few decades, scientists have been intrigued by the potential use of pyrite in semiconductor technology, especially solar cells and other alternative energy applications.
Is there real gold in pyrite
Ironically, pyrite crystals can contain trace amounts of real gold, although it is notoriously difficult to extract. Pyrite-bearing gold is in many cases referred to as “invisible gold” because it is not visible with conventional microscopes but requires sophisticated systematic instruments.
How much gold is in pyrite
Pyrite as gold ore
Some pyrites may contain excess gold of 0.25% or more. Although it is a tiny functional fraction of the ore, the value of gold is so high that pyrite could be worth targeted mining.
