Graphite is used to make carbon steel, pencils, carbon fiber reinforced plastics in car bodies, and negative ends of most batteries (including those in all cell phones, power tools, computers, and hybrid/electric vehicles). Indium is used to make solar cells and liquid-crystal displays (LCDs) in cell phones, computers, and flat-screen television sets. Muscovite is used in heating elements of hair dryers and toasters, joint compound, and cosmetics with a satiny or glittery sheen. Crystals of cultured pure quartz are used to make quartz watches and the frequency controls and timers in every computer and cell phone. Niobium is used to make high-strength noncorrosive steel alloys (for jet engines, power plants) and arc welding rods, plus electrical insulation coatings in cell phones, computers, and electronic games. Tantalum is used to make “tantalum capacitors” that buffer the flow of electricity between a battery and electronic parts in the circuits of cell phones, laptops, iPods, and most other electrical devices. Gallium is used to make light-emitting diode (LED) bulbs and liquid-crystal displays (LCDs) in things like cell phones, computers, and flat-screen television sets. Vanadium is used for cutting tools; mixed with iron to make lightweight shock-resistant steel for car axles and gears, springs, and cutting tools. Bismuth is used as a nontoxic replacement for lead (in ceramic glazes, fishing sinkers, food processing equipment, plumbing, and shot for hunting) and in antidiarrheal medications. Zinc is used to make alloys like brass, skin-healing creams, and galvanized (rust-proof) steel and roofing nails; added to vitamin pills for a healthy immune system and to aid protein production. Barium (Ba) is widely used to make capacitors (that store energy) and memory cells in cell phones and other portable electronic devices. Chromium is used to make stainless steel, yellow and green ceramic glazes and paints, and military camouflage paints; added to vitamin pills for healthy metabolism and lower cholesterol levels. Silver is used to make jewelry and silverware, photographic film, and solder on electrical circuit boards of computers and cell phones. Aluminum is a lightweight silvery metal used to make drink cans, foil, airplanes, and solar panels. Nickel is used to make rechargeable batteries (Ni-Cd) for portable electronic devices, screw-end caps of light bulbs, and stainless steel. Tungsten is a dense metal that makes cell phones and pagers vibrate (by attaching it to an electric motor spinning off center); also used for light bulb filaments, golf clubs, and tungsten carbide cutting tools. Industrial garnet is used as an abrasive in things like sandpaper and sandblasting Copper is used to make copper pipes; electrical wire for homes, businesses, electric motors, and circuit boards in cell phones and other electrical devices. Hybrid cars contain about 100 pounds (45 kg) of copper. Added to vitamin pills for healthy hair and skin. Magnesium is used to make strong, lightweight frames for jet engines and rockets, lightweight cell phone and laptop cases, and incendiary flares and bombs; added to vitamin pills to aid good brain and muscle function and strengthen bones. It is used as table salt, road salt (to melt snow), in water softeners, and as a food preservative. Iron and steel are used to construct machines, buildings, bridges, nails, bolts, tools, file cabinets; iron is added to vitamin pills to aid hemoglobin production in red blood cells for oxygen transport. Calcite is processed into cement, which is used to make concrete. Gypsum is used to make plaster of paris, drywall. and for art (alabaster). It is used to make matches, gunpowder, fertilizer, fungicide, insecticide, and harden rubber (car tires). silver metal (Ag) 62 native silver; galena with Ag as an impurity bauxite is Al ore aluminum (AI) 61 nickel metal (Ni) 59 pyrrhotite contains Ni as an impurity wolframite is W ore tungsten metal (W) >50 garnet (industrial) garnet 46 copper metal (Cu) 33 azurite, bornite, chalcopyrite, chrysocolla, and malachite are Cu ores <25 magnesium metal (Mg) dolomite and olivine are Mg ores salt halite 23 18 iron metal (Fe), steel goethite, limonite, magnetite, and hematite are Fe ores calcite cement 13 12 gypsum sulfur (S) gypsum native sulfur; pyrite is a Sore 6
