Pyrite has the same chemical formula as the rarer mineral Marcasite, but it crystallizes in a different crystal system, thereby classifying it as a separate mineral species. Aggregates of iron sulfide (FeS 2) where the crystal structure cannot be determined without complex analyzing material may be wrongly labeled by dealers. Some Pyrite ...
Iron Pyrite, wholesale, bulk Fools Golds Iron Pyrite Aggregate Scientific Group: Sulfide: Pyrite Chemical Formula: FeS2 Pyrite is the classic "Fool''s Gold". There are other shiny brassy yellow minerals, but pyrite is by far the most common and the most often mistaken for gold. Chispa is the south american name for iron pyrite, fools gold.
What is Pyrite? Pyrite is a brassyellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral.

The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool''s gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite''s metallic luster and pale brassyellow hue give it a superficial resemblance to gold, hence the wellknown nickname ...
Chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ r aɪ t, k oʊ/ KALkoPYryt) is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula CuFeS has a brassy to golden yellow color and a hardness of to 4 on the Mohs streak is diagnostic as green tinged black. On exposure to air, chalcopyrite oxidises to a variety of oxides, hydroxides ...
Marcasite is the lesser known companion of the famous mineral has the same chemical formula as Pyrite, but crystallizes in a different crystal system, thereby making it a scientifically distinct mineral species. Aggregates of iron sulfide (FeS 2) where the crystal structure cannot be determined without complex analysis may be wrongly labeled by dealers and collectors.
A chemical picture of the pyrite oxidation process in the presence of oxygen and water was proposed in the present investigation. The reaction steps of the oxidation mechanism can be separated into two types. Type I reactions present lower activation energies and are redox processes that involve
Pyrite is often confused with the mineral marcasite, a name derived from the Arabic word for pyrite, due to their similar characteristics. Marcasite is a polymorph of pyrite, which means it has the same formula as pyrite but a different structure and, therefore, different symmetry and crystal shapes. The formal oxidation states are, however ...

Name Origin: From the Greek, pyrites lithos, "stone which strikes fire," in allusion to the sparking produced when iron is struck by a lump of pyrite. The mineral pyrite, or iron pyrite, also known as fool''s gold, is an iron sulfide with the formula FeS 2. This mineral''s metallic ...
Iron Pyrite, also known as pyrite, is iron sulfide with FeS 2 as its chemical formula. It resembles gold due to its pale brassyellow tinge and metallic luster, thus it is also called "fool''s gold." It is a common mineral among sulfide minerals.
The mineral pyrite or iron pyrite is commonly referred to as Fool''s Gold because its metallic luster and pale brassyellow 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 .

Pyrite, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, ''fire,'' because pyrite emits sparks when struck by metal. Pyrite is called fool''s gold; to the novice its color is deceptively similar to that of a gold nugget.
Aug 9, 2012 Pyrite, more properly called iron pyrite, is a famous mineral with the chemical formula FeS2 (iron sulphide). Its nickname is "fools gold" owing to its golden color, and it a very common mineral found in a wide variety of environments all over the world. Pyrite is not all that difficult to distinguish from pure gold: It has a hardness of (Mohs) much harder than gold (and ...
