- Clay is a naturally
occurring material composed primarily of fine-grained minerals, which
show plasticity through a variable range of water content, and
which can be hardened when dried and/or fired.
- Clay deposits are
typically associated with very low energy depositional environments such
as large lake and marine deposits.
- Clays are
distinguished from other fine-grained soils by various differences in
composition.
- The term clay refers
to a number of earthy materials that are composed of minerals rich in
alumina, silica and water.
- Clays can also
contain other materials such as iron oxide (rust), silica, and rock
fragments.
- Geosynthetic clay
liners (GCLs) represent a relatively new technology (developed in 1986)
currently gaining acceptance as a barrier system in municipal solid
waste landfill applications.
- The technology of
clays in the field of ceramics, therefor, includes consideration of both
the room-temperature properties and the behavior at elevated
temperatures.
- Most domestic clay
is mined by open-pit methods using various types of equipment, including
draglines, power shovels, front-end loaders, backhoes, scraper-loaders,
and shale planers.
- Processing generally
begins with primary crushing and stockpiling. The material then is
ground and screened.
- Clays usually are
transported by truck from the mine to the processing plants, many of
which are located at or near the mine.
- Clays are used in
the ceramics industries largely because of their contribution to the
moulding and drying properties of the wares
being produced; many
clays, such as the flint clays, are used because of favorable behavior
during firing or because they produce favorable properties in fired
ware.
- The major sources of
imported clay were Brazil (kaolin), Greece (bentonite), Mexico
(activated clay), and the United Kingdom (kaolin).
- Major markets for
exported clays, by descending order of tonnage, were Canada (bentonite
and kaolin), Japan (bentonite and kaolin), Mexico (kaolin), Finland
(kaolin), the Netherlands (bentonite and kaolin), China (kaolin), and
Taiwan (kaolin)
