Sulfur is found naturally around hot springs, volcanoes and in meteorites. It can also be found in cinnabar, gypsum, Epsom salts, stibnite, sphalerite, iron pyrites, barite, celestite and galena.
Sulfur is classified as a non-metal part of the nitrogen family in the periodic table of elements and has an atomic weight of 32.065 with a melting point of 388.36 K. It is the 10th most plentiful element in the universe. Sulfur is pale yellow in color, odorless and appears as a brittle solid. It is not water soluble but is soluble in carbon disulfide. There are eleven isotopes of sulfur. Four isotopes of sulfur are naturally occurring. The majority of sulfur that is produced or collected is used to create sulfuric acid. Sulfuric acid is commonly used to create fertilizers and batteries. To have enough sulfur for commercial purposes, sulfur is harvested from wells in salt domes using hot water. The water is forced into the wells, which melts the sulfur and causes it to rise to the surface of the dome where it can be collected. Sulfur is also found in natural gas and petroleum oil deposits. For the gas and oil to be used commercially, the sulfur has to be removed.
