Zeolite

Zeolites are hydrated crystalline aluminosilicate minerals created millions of years ago after the volcanic eruptions of large quantities of aluminosilicate ash deposited in environments, where there was alkaline water. The interaction of this aluminosilicate ash with alkaline water and the existence of suitable conditions of pressure and temperature have resulted in the creation of zeolites.

The significance of the zeolite for various uses is in the function of its crystalline structure. The structure is tetrahedral and in three-dimensional imaging is celled with the creation of large cavities. These cavities are filled with water molecules and cations. The cations are having the ability to move within these cavities and to be exchanged with other cations without affecting the crystal structure of zeolite. This property is characterized as ion exchange capacity and is very important for the quality of zeolite.

Generally, the amount of water that zeolite can absorb is 60% of its weight.

In nature are found more than 40 species of zeolite (volcanic and sedimentary rocks) from which 20 are located in sedimentary deposits. The zeolites that occur most frequently are: clinoptilolite, mordenite, chabazite, analcime, phillipsite, erionite and heulandite. The most important of these is the clinoptilolite. Also, more than 150 synthetic zeolites have been manufactured for various uses. The most known is zeolite A (usually used as a laundry detergent), zeolites X and Y (used as catalytic cracking) and oil catalyst ZMS-5.

Applications of Zeolite

  • Agriculture
  • Livestock Farming
  • Water Purification
  • Pets
  • Soil Decontamination
  • Building Materials
  • Paper Industry
  • Solar Energy Storage
  • Wastewater Treatment

Generally, the use of zeolites can vary. Our company’s products are mainly targeted for agricultural and livestock uses. The application in these categories are further analized in the respective sections. Briefly, some of the other zeolite applications are for softening systems (ion exchange filters) and water filtration, as pet litter, in the neutralization of radioactive wastes and to clean contaminated soil by toxic heavy metals, as building materials, in paper industry, and others.

Greek Zeolite

The Greek zeolite is clinoptilolite of sedimentary origin with clinoptilolite content up to 85%, average content 80% (XRD Analysis Mineral Lab USA) with content in heavy metals Lead, Cadmium and Arsenic below the international specifications (Certified Analysis Lab QLAB Thessaloniki). The complete spectroscopy and quality evaluation of the Greek Zeolite has been done by the University of Athens- Minerology Laboratory- Geology Sector.

The granular analysis is followed up from the National Research Center and Technology (CERTH).

The company OLYMPUS SA is the only one company in the sector, which beyond the import and commercialization of zeolite, is active intensively in the research, development and exploitation of zeolitic deposits in the Greek Territory.

The first results, in the phase of the Research License, that came out from the geological research, as far as it regards the quality of the material in the holding area (Kokkalo-Petroton) gave significantly satisfactory results (content in clinoptilolite is > 85%). In November 2017 OLYMPUS SA conducted a research drilling program of the licensed area in Kokkalo. More information related with the results in the “Research and Development” sector.
