PYRITE FOR SALE. The mineral pyrite or iron pyrite is commonly referred to as Fool's Gold because its metallic luster and pale brass-yellow hue give it a superficial resemblance to gold. In the old mining days, pyrite was sometimes mistaken for gold. Pyrite is the most common of the sulfide minerals with the chemical formula FeS2.

The formula of pyrrhotite minerals can also be expressed as Fe n−1 S n with n ≥ 8 to give structures from Fe 7 S 8 to Fe 11 S 12. The most iron Fe-deficient end member, Fe 7 S 8, has a monoclinic symmetry, whereas the intermediate (Fe 1−x S) and equimolar (FeS) members have hexagonal and orthorhombic structures, respectively [ 80, 81 ].

What is Pyrite? Pyrite is a mineral of iron, having iron disulfide in an isometric crystal system. This substance is also known as iron pyrite or fool's gold. The chemical formula of this mineral is FeS2, while the formula mass of this substance is 119.98 g/mol. Moreover, it is the most abundant sulfide mineral on Earth.

Pyrite is a sulfide mineral containing iron (Fe) and sulfur (S) as structural elements. Its chemical formula is FeS 2. It is also known as iron pyrite and "fool's gold" due to its pale-brass yellow color. In the ancient days, people misunderstood pyrite as gold since it possesses a yellowish metallic luster similar to gold.

Oxide Analysis Formula; Notes. Pyrite is quite hard (6.0-6.5 Moh) and is even used in resin bonded abrasives (i.e. brake linings). It is difficult to grind and clay materials containing pyrite can fire with an iron-speckle (in accordance with the size of the iron pyrite particles). This effect is much sought after in buff and brown/red firing pottery clay bodies burned in reduction firing.
