Chemistry of Sulfur (Z=16) Chemistry LibreTexts

Sulfur also takes on many forms, which include elemental sulfur, organosulfur compounds in oil and coal, H 2 S(g) in natural gas, and mineral sulfides and sulfates. This element is extracted by using the Frasch process (discussed below), a method where superheated water and compressed air is used to draw liquid sulfur to the surface.
