Our Australian Zeolite

CMZeolites Rock

CMZeolites is an Australian deposit of carboniferous age and dates to 300-330 million years old and is one of the oldest commercial deposits in the world.

Our Zeolite was formed when volcanic ash fell or washed into a semi saline lake or body of water and was compressed overtime, this process is known as Zeolitization. Variables such as temperature, geographic location, water to ash ratio, salt content of the water, contribute to our deposit’s unique composition, and therefore Zeolites are not created equal or the same.

Our Zeolite is very hard and is rated greater than 5 on the Mho's scale for hardness. Other deposits especially in Europe are much younger and softer. Having a harder Zeolite is beneficial for many applications where you do not want the Zeolite to breakdown, such as in water and air filtration systems. 


Features of CMZeolites

  • Very hard deposit (Mho's index >5)
  • Lighter than sand
  • Binds heat for plants in winter
  • Cools plants with watering in summer
  • Uniform product with consistent density
  • Forms sol (single phase) with finest particulates (ANZ19)
  • Very hydrophilic
  • Doesn’t bind much water
  • Slow release of water
  • Environmentally safe
  • Very high crystallinity
  • High content of Clinoptilolite and Mordenite
  • High CEC (Cation Exchange Capacity)
  • Blocky irregular shapes, great for filtration or use in soil or potting mixes

Benefits of CMZeolites

  • Does not break down
  • Easier to backwash
  • Greater growth
  • Reduced liklehood of dehydration and wilting 
  • No wet patches in media
  • Shares water evenly
  • Attracts water
  • Doesn't fluidise media 
  • Maintains moisture in soil which is available to plants
  • As above 
  • No muddying of media
  • High concentration of zeolites
  • High binding capacity for cations including ammonium ions
  • High AFP (Air Filled Porosity) for oxygenation of plant roots

Mineralogy of Zeolites

Zeolites are a group of naturally occurring aluminosilicate minerals. There are some 46 different Zeolites and only four of them have the absorption characteristics that render them of commercial value. In order, these are Clinoptilolite, Mordenite, Chabazite and Phillipsite with ours containing the best of these two being 85% Clinoptilolite and 15% Mordenite. 

Uniqueness of CMZeolites

The absorption characteristics of CMZeolites are what makes it a "marvellous mineral". Its porous honeycomb three-dimensional structure is mainly occupied by water and cation molecules, which can gain and lose water reversibly. It can exchange cations the most important being ammonium ion, and they do this without change to its physical structure. Heavy metal ions are effectively not exchangeable and are bound such as lead (Pb), mercury (Hg) and cadmium (Cd).
