Bromine Bromine compounds are used in flame retardants (such as those found in elec- tronic appliances), drilling fluids, pesticides (such as methyl bromide), water treatment, dye manufacture, insect repellents, perfumes, pharmaceuticals, pho- tographic chemical, and intermediate chemicals for the manufacture of other chemical products. Leading mine producers are the United States, Israel, China, Jordan, Japan, Ukraine, Azerbaijan, Germany, and India. Cadmium Most cadmium is used in cadmium-nickel batteries. It is also used in pigments, coatings and platings, stabilizers for plastics, nonferrous alloys, and photovoltaic devices (though health concerns have led to the diminished use of cadmium in these latter applications). Leading refinery producers are China, South Korea, Kazakhstan, Canada, Japan, Mexico, Russia, the United States, Germany, India, the Netherlands, Peru, and Australia. Cement Cement constitutes portland, masonry,and clinker cement, anditis used primar- ily by producers of ready-mixed concrete and secondarily by contractors and building materials dealers. Leading producers are China, India, the United States and Puerto Rico, Japan, Russia, South Korea, Spain, Brazil, Turkey, Italy, Egypt, Mexico, Indonesia, Thailand, Iran, Germany, Saudi Arabia, Pakistan, France, and Vietnam. Cesium Cesium is used primarily in cesium formate brines, a dense liquid used as a drill- ing fluid in oil and gas wells. It is also used in atomic clocks, where its vibration maintains accuracy to a few hundred trillionths of a second, which is key to syn- chronizing satellite and Internet communications as well as missile guidance sys- tems. Cesium plays a role in DNA separation methods, infrared and night vision instruments,photoelectric cells, andtraffic control devices. Radioactiveisotopes of cesium areused in treating cancerand in a varietyofscientific, industrial, and med- ical instruments. The leading producer of pollucite concentrate, the source of most cesium,is Canada;reserves arelocated inCanada, Namibia, andZimbabwe. Global Resources Major Worldwide Mineral Resources and Producers • 1393 Resource Description and Leading Producers Chromium A strategic resource, chromium is used in the produciton of alloys and superal- loys, stainless steel, refractory materials, pigments, and chemicals. It is also used for dyeing textiles, inleathertanning, and in cleansers of laboratory glassware. In its trivalent oxidation state, chromium is an essential trace nutrient for humans and other mammals. Leading world mine producers include South Africa, Ka- zakhstan, and India. Clays Clays include ball clay, bentonite, common clay, fire clay, fuller’s earth, and ka- olin, used in a wide variety of applications, including floor and wall tiles, sanitaryware, absorbents, drilling muds, foundry sand bonds, iron ore pelletiz- ing, bricks,lightweight aggregates, cement,sewerpipes, roofingtiles,flower pots, refractory products, and paper.

They are used in jewelry, carvings, collections, ornamen- tation for furnishings, and artworks. The industrial uses of natural gemstones such as diamond and garnet have largely been taken over by their synthetic ver- sions. Leading producers of gemstones include Botswana, Russia, Canada, An- gola, South Africa, the Democratic Republic of the Congo, Namibia, Guinea, Ghana, Sierra Leone, the Central African Republic, Guyana, Australia, Tanzania, Côte d’Ivoire, Brazil, and China. Germanium Germanium and its compounds are found in fiber-optic devices, infrared optics, polymerization catalysts, electronics, and solar electric applications. The leading world refinery producer is the United States. Gold Gold is used in jewelry, artworks, electrical devices, electronics, and dental work. China is the leading gold-producing nation,followedby South Africa, the United States, Australia, Peru, Russia, Canada, Indonesia, Ghana, Papua New Guinea, Chile, Mexico, Brazil, and Uzbekistan. Graphite Natural graphite has a broad variety of uses, including refractory applications, steelmaking, foundry operations, brake linings, batteries, and lubricants. Mine producers are led by China, follwed by India, Brazil, North Korea, Canada, Mex- ico, Ukraine, Madagascar, Sri Lanka, the Czech Republic, Turkey, and Norway. Gypsum Gypsum is used in the manufacture of wallboard and plaster products, agricul- ture (in soil amendments), smelting, glassmaking, and other industrial applica- tions. Leading mine producers are China, the United States, Iran, Spain, Thai- land, Canada, Mexico, Japan, Italy, France, Australia, India, Russia, Egypt, Brazil, Germany, the United Kingdom, Poland, Algeria, Austria, and Uruguay. Global Resources Major Worldwide Mineral Resources and Producers • 1395 Resource Description and Leading Producers Helium Helium is used in cryogenics, pressurizing and purging, welding cover gas, con- trolled atmospheres, leak detection, and breathing mixtures. Leading producers are the United States, Algeria, Qatar, Russia, and Poland. Indium Indium is used primarily in the production of indium tin oxide (ITO) for ITO thin-film coatings in electrical conductors used in flat-panel devices and liquid crystal displays (LCDs). It is also used in alloys, compounds, electrical compo- nents, semiconductors, and research. World refinery producers include China, Ja- pan, South Korea, Canada, Belgium, Russia, and Peru. Iodine Iodine isused in intermediate compoundssuch as ethyland methyl iodide,crude iodine, potassium iodide, sodium iodide, povidine-iodine (iodophors), and ethylenediamine dihydroiodide. End uses are found in the pharmaceutical and sanitation industries—for example, in contrast media used for X-ray imaging. Io- dine was once used in coatings for film, but digital imaging has led to a decline in that use. Iodine is also an essential dietary mineral. The leading producer is Chile, distantly followed by Japan, China, Turkmenistan, Azerbaijan, Russia, In- donesia, and Uzbekistan. Iron ore Iron ore is mined to extract iron for intermediate processing as concentrates, coarse ores, fine ores, pellets, briquettes, and sinter. Primary end uses are in wrought and cast ironsandas the primary alloy in steel manufacture.Theworld’s leading mine producer is China, followed by Brazil, Australia, India, Russia, Ukraine, the United States, South Africa, Canada, Iran, Sweden, Kazakhstan, Venezuela, Mauritania, and Mexico. Kyanite and related minerals Most kyanite (in the form of kyanite-mullite) is used in refractories, of which more than half is in turn used for ironmaking and steelmaking and the rest for the production of chemicals, glass, nonferrous metals, and other materials. The world’s leading mine producer is South Africa, followed by the United States, France, and India. Lead Themajor use oflead isinlead-acid batteries(which are usedin igniters andstart- ers), with the remainder used mainly in ammunition, casting material, pipes, sheets (such as those used fo block radiation), traps, extruded products, cable coverings, caulking lead, solders, oxides for ceramics, chemicals, glass, pigments, counterweights, brass andbronze, foil, terne metal,type metal, andwire. Primary mine producers include China, Australia, the United States, Peru, Mexico, Can- ada, India, Sweden, Ireland, Poland, South Africa, Kazakhstan, and Morocco. Lime Lime is used in the steelmaking, flue gas desulfurization, construction, water treatment, mining, precipitated calcium carbonate, and pulp and paper indus- tries. Leading producers are China, the United States,Japan(quicklime),Russia, Germany, Brazil, Mexico, Italy, France, Turkey, Iran, Belgium, Canada, Vietnam, the United Kingdom, Poland, Austria, and South Africa. Lithium Lithiumis used inbatteries, ceramics andglass, lubricating greases, pharmaceuti- cals and polymers, air-conditioning, primary aluminum production, continuous casting, and chemical processing. Leading mine producers are Chile, Australia, China, Argentina, Canada, Portugal, Zimbabwe, Brazil, and the United States. .
