St. Cloud Natural Zeolite (Clinoptilolite)
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Natural zeolites are microporous volcanic minerals with sieving and cation exchange properties for use in agriculture, environmental and industrial applications. Features such as a vary large internal surface area in the porous structure and exchangable cations lead to a variety of uses. It is used as an animal feed supplement that has been shown to improve health and reduce the negative effects of animal waste; as an additive to animal stalls and pens to reduce ammonia and other emissions to air and water; as a soil amendment to retain water and plant nutrients in root zones, which conserves both; for a number of other horticultural and agricultural uses, including being endorsed for use in space by NASA; as a water filtration media that removes ammonia, some heavy metals and other constituents; etc.

Major exchangeable cations are Rb, Li, K, Cs, NH4, Na, Ca, Ag, Cd, Pb, Zn, Ba, Sr, Cu, Hg, Mg, Fe, Co, Al, Cr. Primary adsorbing gases are CO, CO2, SO2, H2S, NH3, HCHO, Ar, O2, N2, H2O, He, H2, Kr, Xe, CH2OH, Freon, formaldehyde, and mercaptans.

Product mined near Winston, New Mexico, USA.
