- Asbestos is a group
of minerals with long, thin fibrous crystals. The word "asbestos" is
derived from a Greek adjective meaning inextinguishable.
- The Greeks termed
asbestos the "miracle mineral" because of its soft and pliant
properties, as well as its ability to withstand heat.
- When asbestos is
used for its resistance to fire or heat, the fibers are often mixed with
cement or woven into fabric or mats.
- There are six types
of asbestos. They are actinolite, amosite, anthophyllite, crocidolite,
tremolite, and chrysolite.
- Asbestos deposits
are found underground, and the ore is brought to the surface for
processing using conventional mining practices.
- Chrysotile asbestos
is usually found near the surface and can be accessed with an open-pit
mine. Other asbestos deposits are found at varying depths and may
require tunnels as deep as 900 ft to gain access.
- Asbestos fibers are
formed by the gradual growth of mineral crystals in cracks, or veins,
found in soft rock formations.
- The crystals grow
across the vein, and the width of the vein determines the resulting
asbestos fiber length. Because the minerals come from the surrounding
rock, the chemical composition of the fibers is similar to the rock.
- As a result the
asbestos must be separated from the rocky ore using physical methods,
rather than the chemical methods sometimes used to process other
ores.
- Asbestos is used in
brake shoes and gaskets for its heat resistance.
- In the past was used
on electric oven and hotplate wiring for its electrical insulation at
elevated temperature.
- Asbestos is used in
buildings for its flame-retardant and insulating properties, tensile
strength, flexibility, and resistance to chemicals.
- In Japan,
particularly after World War II, asbestos was used in the manufacture of
ammonium sulfate for purposes of rice production, sprayed upon the
ceilings, iron skeletons, and walls of railroad cars and buildings and
used for energy efficiency reasons as well.
- In the past asbestos
was used as insulation in U.S. and Canada.
- Sales and use of
asbestos increased to meet the demands of these new and expanding
markets.
- Greece was importing
about 30,000 t/yr of asbestos for its own asbestos-cement industry
.
- As with many of the
industrial minerals mining industries in China, accurate production and
trade data on asbestos are difficult to obtain and frequently are not
available.
- In the United
Kingdom T & N extended its interests in asbestos products by
expanding the capacity of its existing asbestos cement, textiles and
friction materials factories.
