Zinc
Zinc
is a versatile mineral that we encounter in our daily lives. Zinc is found in a variety of
products including zinc creams, sunblocks and vitamins. However, zinc is primarily used
for the galvanizing of steel, for die-castings and in the production of brass and zinc
oxides.
Did you know? The largest zinc mine
in the world is the Red Dog Mine operated by Cominco Alaska Inc. and is located in Alaska,
north of the Arctic Circle.
Health - Zinc is essential to
both our physical and mental health. From healthy skin, hair and nails, to muscle, nerve
and brain functions, zinc plays a key role. Teeth, bones, the healing process, and the
immune and reproduction systems are all dependent on a sufficient amount of zinc in our
bodies.
Transportation Zinc castings, which have
excellent dimensional stability, are used in everything from automobiles and electronic
components to childrens toys. Zinc components can be large, such as truck axle tubes
or so small that they are barely visible and weigh only a fraction of an ounce.
Todays automobiles contain about 40 pounds of zinc, primarily in the zinc coating on
galvanized steel body panels. The delicate instrument panels in todays jet airliners
are fabricated from zinc. And todays ship builders use zinc anodes to protect the
steel hulls of ships against the highly corrosive effects of salt water.
Home Furnishings Your refrigerator,
dishwasher, washing machine and clothes dryer are just a few of the labor-saving
devices in your home that contain a host of zinc die-cast components. Zinc sulfide enables
your TV picture tube to display blue and green. Zinc is alloyed with copper to form brass,
which increases the strength and castability, and imparts an appealing golden color.
Outside Your Home Builders depend on the
structural strength and corrosion resistance of zinc-coated (galvanized) steel. Products
include structural framing, railings, garage doors, roofing, pre-painted exterior wall
panels and zinc-protected fastening devices, such as screws, nails and brackets. In your
yard, such everyday functional and recreational items as garbage cans, swing sets, fences
and gates, garden tools, patio furniture, storage sheds, cutters and swimming pools all
contain zinc, the one metal that assures maximum rust protection.
Did you know? Zinc is called the
Great Protector it is used to protect metals (galvanizing) as well as humans, in
products such as sun screen (zinc oxide), zinc lozenges, or vitamins.
Did you know? Since 1982 U.S. minted
"copper" pennies have actually been 97.6 percent zinc, with just a 2.4 percent
copper coating.
Zinc Fact In 1996, an estimated 355,000 tons
of zinc in waste and scrap was recovered in the form of slab zinc, brass, zinc-base
alloys, dust, oxide, and other chemicals.
Zincs Future One of zincs major
advantages is that it is recyclable. In North America alone, approximately one third of
the zinc consumed annually comes from recycled material. The zinc industry is firmly
committed to increasing that ratio, further reducing the requirements for virgin ores,
energy, air and water.
