Since 1960, G.Apostolico & C.Tanagro
s.n.c. company has exploited their own mineral deposits of campanian
ignimbrite, sited in South Italy by the North-East side of the Vesuvio,
widespread over about 200.000 m2.
This volcanic deposit was emplaced about 30.000 years ago after a
huge eruption of Campi Flegrei , post-eruptive mineralization processes
led to the crystallization of a precious minerals called “ zeolite
“; this word derives from Greek << zeo-lithos >>
that means << boiling stone >>
But what are zeolites?
Zeolites are hydrated alkaline and alkaline-earth aluminosilicates
with exclusive chemical-physical properties as: high cationic exchange
capacity and considerable attitude to water absorption and desorption.
These properties come from an unusual crystalline structure, characterized
by cavities and channels which host extremely mobile ions and water
For their features, zeolites have found in the last years considerable
applications in zootechny, agriculture as well as some environmental
fields, leading the scientific and commercial interests to unimaginable
dimension up to some years ago.
In order to guarantee the quality of our zeolite products, our company
respects two essential rules:
- strict characterization of the mineral deposits
- wise manufacture of the raw materials and updated technologies.
The program on which our company has organized his project consists
in: full experience and high professional advices.
