Clinoptilolite and mordenite are two of the most important minerals naturally found in zeolite deposits. Both belong to the aluminosilicate family and are highly valued for their ion-exchange and adsorption properties, making them essential in agriculture, animal feed, deodorization, and environmental treatment applications.
Medium-grade natural zeolite refers to deposits that contain a balanced composition of clinoptilolite, mordenite, and silica minerals such as quartz. With an active zeolitic mineral content typically ranging from 40–70%, this grade offers an ideal balance between adsorption capacity, cation exchange activity, and mechanical stability. It is widely utilized across industrial and agricultural sectors where cost efficiency and consistent performance are critical.
This type of zeolite performs effectively in fertilizer formulations, feed additive production, and deodorizer applications, providing dependable ammonia adsorption and nutrient retention while maintaining high physical durability during processing, transport, and use.
PT Excellent Zeolit Indonesia supplies medium-grade natural zeolite from Sukabumi, West Java, composed of a natural combination of mordenite and clinoptilolite with a relatively high quartz content. This mineral composition ensures a strong balance between functional performance and physical stability, making it well-suited for fertilizer, feed additive, and agricultural applications in both regional and international markets.
Mineral Composition of PT Excellent Zeolit Indonesia
According to XRD analysis by Sucofindo Laboratory (Report No. E00395/ANAAAS, April 2025), the zeolite powder sample from Cikembar, Sukabumi, West Java contains the following minerals:
| Mineral | Composition (%) |
|---|---|
| Quartz (SiO₂) | 57.0 |
| Mordenite | 29.0 |
| Clinoptilolite | 12.4 |
| Heulandite | 1.6 |
With a total of approximately 43% active zeolitic minerals (Clinoptilolite + Mordenite + Heulandite), the zeolite supplied by PT Excellent Zeolit Indonesia is classified as a Medium-grade natural zeolite, offering sufficient active mineral content for agricultural and livestock applications. This natural blend delivers a strong balance between adsorption efficiency, nutrient retention, and material stability, making it suitable for various industrial and agricultural uses.
Key Advantages
- High mordenite content (29%) – Excellent for ammonia adsorption, odor control, and moisture regulation, ideal for deodorizer and feed additive applications.
- Clinoptilolite presence (12.4%) – Provides cation-exchange activity that enhances nutrient retention and supports soil improvement in fertilizer formulations.
- High quartz ratio (57%) – Improves mechanical strength and durability, ensuring the zeolite remains stable during handling, mixing, and transportation.
- Stable natural source – Mined from Cikembar, Sukabumi, Indonesia, with a consistent clinoptilolite–mordenite composition that ensures reliable supply and uniform performance.
- Ready to use – Naturally effective for agriculture, deodorizer, and feed additive industries without requiring activation or chemical treatment.
Limitations and Market Position
For high-grade feed additive markets such as Europe, buyers often require zeolite with clinoptilolite content above 70%. For these premium segments, additional enrichment or beneficiation may be needed to increase zeolitic concentration.
However, for Southeast Asian, African, and South Asian markets, this medium-grade composition remains highly competitive, practical, and cost-efficient, offering the ideal balance between quality and economic value for large-scale agricultural and environmental applications.
Main Target Segments
- Fertilizer manufacturers seeking natural carriers and soil enhancers.
- Feed and livestock producers focused on affordable, functional raw materials.
- Deodorizer and farm hygiene distributors requiring natural absorbents.
- Aquaculture and agricultural sectors looking for dependable zeolite sources for water and soil improvement.
Application Implications
| Application | Relevance | Remarks |
|---|---|---|
| Feed additive / deodorizer | ★★★★☆ | High mordenite content enables excellent ammonia (NH₃) and toxin absorption. |
| Fertilizer carrier / soil conditioner | ★★★★☆ | Balanced quartz and zeolite composition improves soil aeration and nutrient retention. |
| Water purification / filtration | ★★★☆☆ | Effective for ion exchange, though higher quartz content slightly reduces CEC. |
