Pyrite

Pyrite, also known as "gold dupes" because of its golden metallic gloss, is an iron sulfide metal and is one of the most diverse sulphide metals in nature.

Composition Method

Pyrite is formed in different geological environments as a result of chemical reactions between iron and sulfur, the most prominent methods of its composition:

Composition in hydrothermal environments: Deposition of hot solutions rich in sulfide and iron in mineral veins.

Sedimentary composition: deposited in clay rock and limestone as a result of the activity of sulphur-reduced bacteria.

Composition in fiery and mutant rocks: small crystals are found in some granite and chestnut rocks.

Interaction with organic substances: Sometimes formed as a result of the degradation of organic substances in sulfur-rich environments.

Composition Environment

Hydrothermal environments: It is found in metal veins accompanying sulphides such as galina and spalierite.

Sedimentary environments: shown in mud rocks and limestone rich in organic matter.

Fiery and mutant rocks: It is found in granite, chestnut and nice, where it crystallizes from magma or during transformation processes.

Coal and clay rock deposits: The result of bacterial activity reduces sulfates to iron sulfide.

Chemical Formula

FeS2

It consists of iron (Fe) and sulfur. (S)

Physical Properties: Yellow metal with gold resembling iron sulfide (FeS2), characterized by a metal luster and hardness ranging from 6 to 6.5 on a mousse scale.

Crystal Composition

(Isometric - Cubic System)

There are predominantly in cubic crystals or eight facets, as can be seen in granular or mass aggregations. It features a glossy brass yellow color and metallic luster.

Most important uses

Sulphur production and sulphuric acid: used as the main source of sulphur production.

Fertilizer and insecticide industry: enters into the production of some agricultural chemicals.

Iron production: Sometimes used as a secondary source of iron extraction.

Glass and ceramic industry: enters as an additive to give special colors.

Study of ancient geological environments: used as evidence of chemical conditions in ancient geological times.

Locations in Saudi Arabia

Al-Birit is located in several areas rich in mineral ores in the Arab Shield, including:

Gold cradle Medina region: with gold and copper deposits in hydrothermal veins.

Mount Sayyad, north of Medina, is accompanied by copper ores and sulphides among others.

Fatima Valley near Makkah: There are some deposits rich in sulphides.

Largest exporters: Spain, Italy and the United States are among the largest exporters of Peret.
