Product

Clinoptilolite is the principal natural zeolite ore used commercially, valued for its high cation‑exchange capacity, thermal stability, and benign toxicity profile.

Identity and composition

• Mineral type: Natural zeolite, tectosilicate aluminosilicate.

• Typical formula: (Na,K,Ca)₂₋₃Al₃(Al,Si)₂Si₁₃O₃₆ ⋅ 12H₂O (variable Na/K/Ca content and Si/Al ratio).

• Key physical traits: Microporous framework, high internal surface area, strong selectivity for NH₄⁺ and some heavy‑metal cations, stable up to ~600–700 °C.

Main applications

• Environmental and water treatment: Removal of ammonium, heavy metals, and radionuclides from municipal, industrial, and aquaculture wastewaters; odour and emission control in waste and manure.

• Agriculture and animal nutrition: Soil amendment for water and nutrient retention; feed additive to bind ammonia and mycotoxins, improve litter quality, and reduce odour and nitrogen losses.

• Construction and materials: Additive in cement, concrete, mortars, and asphalt to improve durability, shrinkage, and pozzolanic behaviour; filler in polymers and coatings.

• Health and veterinary products (growing but niche): Detox/“binder” supplements, antidiarrheal and hemostatic preparations, and GI‑support products, generally using purified or micronized grades; safety supported but still under active study.

Commercial forms and grades

• Ore and milled grades: Crushed, screened, and milled powders or granules (e.g. 0–0.5 mm, 0.5–1.5 mm, 2–5 mm) for bulk uses in agriculture, filtration, and environmental remediation.

• Activated / modified grades: Thermally activated, acid‑treated, or surface‑modified clinoptilolite to enhance adsorption of specific ions (Pb²⁺, Cd²⁺, As³⁺, VOCs) or improve compatibility with polymers and cements.

• Feed and food‑grade products: Tight particle‑size and purity specs, low heavy‑metal content, and regulatory compliance for animal feed additives and human dietary supplements.

Typical properties for a data sheet

• Mineralogy: ≥ 60–90% clinoptilolite in commercial concentrates, with quartz, feldspar, and clays as main impurities.

• Bulk density: Roughly 0.7–0.9 t/m³ (loose, granular) depending on grade.

• Cation exchange capacity: Commonly in the range 1.5–2.5 meq/g (with high selectivity for NH₄⁺, K⁺, Na⁺, some heavy metals).

• pH in water: Typically near neutral to slightly alkaline for unmodified material.
