Sulfur or sulphur is a chemical element with symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S 8.
Frasch process, method of mining deep-lying sulfur invented by the German-born American chemist Herman Frasch. The process involves superheating water to about 170 °C (340 °F) and forcing it into the deposit in order to melt the sulfur (melting point of about 115 °C, or 240 °F), which is lifted
From the late 1800s to the end of the 20th century, the Frasch process of sulfur mining was commonly used. During the latter part of the 20th century, mining or recovering sulfur as a by-product of natural gas production or oil refinement became more significant.

The Frasch process is a method to extract sulfur from underground deposits. It is the only industrial method of recovering sulfur from elemental deposits. Most of the world's sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas sources became more commonplace (see Claus process).
Simple refineries can only process light crudes with a low sulphur content (sweet). Complex refineries have the ability to process heavier feedstock with a much higher sulphur content (sour). Complex refineries have the ability to process heavier feedstock with a much higher sulphur content (sour).
