Encyclopedia of Global Resources part 128

Encyclopedia of Global Resources part 128 provides a wide variety of perspectives on both traditional and more recent views of Earth's resources. It serves as a bridge connecting the domains of resource exploitation, environmentalism, geology, and biology, and it explains their interrelationships in terms that students and other nonspecialists can understand. The articles in this set are extremely diverse, with articles covering soil, fisheries, forests, aluminum, the Industrial Revolution, the U.S. Department of the Interior, the hydrologic cycle, glass, and placer mineral deposits. . | 1176 Sulfur Global Resources U.S. End Uses of Sulfur Metal Source Data from the U.S. Geological Survey Mineral Commodity Summaries 2009. U.S. Government Printing Office 2009. Note Approximately 90 percent of sulfur is used in the form of sulfuric acid. Other uses occur in many industries because many products require sulfur during their manufacture. in dyeing in clearing water in public systems and plant-related processes such as sugar manufacture and in porcelain and other cements. Gypsum calcium sulfate dihydrate and its partially and completely dehydrated forms plaster of paris and anhydrite are useful in construction work including use in some cements which are otherwise roasted clay-limestone products. Sulfides of importance are principally the ore minerals mentioned above sulfides of mercury zinc and cadmium are used as pigments. Elemental sulfur is used as a vulcanizing agent for rubber and appears in crop-dusting formulations. Among manufactured organic sulfur compounds detergents probably head the volume list. These are organic sulfonates with a long carbon chain the molecule forms a bridge between the water-soluble sulfonate end and the grease-soluble carbon end allowing greasy dirt to be rinsed away. Many pharmaceutical compounds such as the sulfa drugs the penicillins certain vitamins saccharin and other drugs have one or more sulfur atoms built into their molecular structures. Robert M.
