MiningKaolin is usually
transported by truck from the mine to the
processing plants, many of which are located at or
near the mine.
In our words: Picking kaolin up in a truck and
taking it to the plant.
StockpileClay Grades
A large supply of kaolin is gathered and held in reserve for use during a shortage or during a
period of higher prices.
In our words: Putting kaolin in a big stack so
you don’t run out.
Blending
…mixing different types of kaolin to achieve
optimum mix of particle size, and to equalize
variation of mix
In our words: mixing it up
Blunging
The kaolin is mixed with water and chemicals to create milk-shake-like
slurry. Slurry is simply the water and dispersed clay
mixture.
In our words: mixing the kaolin with water
Degritting
The slurried kaolin is transported through
pipelines where sand, mica and other impurities are
extracted with the help of gravity.
In our words: You are taking out the stuff you
don’t want
Mine Storage
…the storage of products in silos and
tanks
In our words: putting the kaolin in tanks
Pipeline
A pipeline is a long tubular conduit with pumps and valves for flow control; it is also used to transport kaolin over distances.
In our words: runs the kaolin to the places it
needs to go
PlantThe equipment and buildings
necessary to carry on kaolin
manufacturing is the plant.
In our words: a building where
they make kaolin
Plant Storage
…the storage of products in silos
and tanks
In our words: keeping the
kaolin in tanks
Screening
Screening the kaolin is passing it through meshed material to remove larger
pieces that are not needed.
In our words: kaolin is run through a screen where large
pieces are taken out.
Magnetic SeparationThe kaolin slurry is pumped through highly compressed fine stainless steel wool. When it is energized, it separates the
magnetic minerals and allows the non-magnetic kaolin to pass through.
In our words: The magnet helps take out the stuff they don’t want in the kaolin.
Plant Storage
…the storage of products in silos
and tanks
In our words: keeping the
kaolin in tanks
Classification
…organizing the kaolin by classes or
types.
In our words: puts the kaolin with
others like it
Plant Storage
…the storage of products in silos
and tanks
In our words: keeping the
kaolin in tanks
Screening
Screening the kaolin is passing it through
meshed material to remove larger pieces that
are not needed.
In our words: kaolin is run through a screen
where large pieces are taken out.
Leaching
Leaching the kaolin involves dissolving
out the soluble parts by percolation.
In our words: boiling the kaolin to take out the parts they don’t
want.
Plant Storage
…the storage of products in silos
and tanks
In our words: keeping the
kaolin in tanks
Filtration
Large rotary vacuum filters remove water
from the slurried kaolin.
In our words: It takes the water out of the kaolin
Plant Storage
…the storage of products in silos and tanks
In our words: keeping the
kaolin in tanks
Screening
Screening the kaolin is passing it through
meshed material to remove larger pieces that
are not needed.
In our words: kaolin is run through a screen
where large pieces are taken out.
Spray Drying
Spray drying kaolin is a method of producing a
dry powder from a slurry by rapidly drying
it with a hot gas.
In our words: spraying it with hot air to dry it
ShippingShipping involves shipping the kaolin to other parts of the country
and world.
In our words: Sending the kaolin to the people who buy it.
