Fourth most abundant element in the earth's crust (56,300 ppm). Ninth most abundant element in the universe. Used in steel and other alloys. Essential for humans. It is the chief constituent of hemoglobin which carries oxygen in blood vessels. Its oxides are used in magnetic tapes and disks. Obtained from iron ores. Pure metal produced in blast furnaces by layering limestone, coke and iron ore and forcing hot gasses into the bottom. This heats the coke red hot and the iron is reduced from its oxides and liquified where it flows to the bottom 01z4tnBbsL0 Iron
By the 3rd century, the Chinese discovered that sulfur could be extracted from pyrite.

Indian alchemists wrote extensively about the use of sulfur in alchemical operations with mercury, from the eighth century AD onwards.

In 1777, Antoine Lavoisier helped convince the scientific community that sulfur was an element, not a compound. شناخته شده برای مردم باستان؛ در زمان پیدایش به عنوان گوگرد شناخته میشده 26 From the Anglo-Saxon word "iron" or "iren" (the origin of the symbol Fe comes from the Latin word "ferrum" meaning "iron").

Elemental sulfur is considered to be of low toxicity
Penicillin is a natural, sulfur-based antibiotic
Sulfur's main commercial use is as a reactant in the production of sulfuric acid.

Sulfur is a component of black gunpowder, and is used in the vulcanization of natural rubber and a fungicide.

It is used to make sulfite paper and other papers, to fumigate fumigant, and to bleach dried fruits.

It is also used extensively in making phosphatic fertilizers.
