Product Overview

Nature's Most Absorbent Mineral — Straight from the Earth

Raw sepiolite ore is a hydrated magnesium silicate clay mineral with a unique fibrous microstructure that gives it extraordinary absorptive and adsorptive properties. Our raw ore is extracted from open-pit mines in Turkey's Eskisehir and Sivrihisar regions, home to the world's largest and highest-quality sepiolite reserves.

Unlike processed grades, raw sepiolite ore retains its full natural fiber length and crystalline integrity. This makes it the preferred starting material for clients who operate their own grinding, granulation, or calcination facilities and need maximum control over their end product's characteristics.

Each shipment is accompanied by a detailed Certificate of Analysis covering chemical composition, moisture content, and particle size distribution. We work closely with buyers to ensure the raw material meets their specific processing and quality requirements.

The mineral's natural porosity — with channels measuring approximately 3.7 x 10.6 angstroms — enables remarkable absorption capacity. Raw sepiolite ore can absorb up to 2.5 times its weight in liquid, making it one of the most efficient natural sorbents available in the industrial mineral market.

Applications

Where Raw Sepiolite Ore Is Used

Raw sepiolite ore serves as the foundational material for a wide range of industries. Here are the primary sectors where our raw ore is sourced and processed further.

🐾

Pet Care & Cat Litter

The most significant end-use market for sepiolite. Raw ore is granulated into highly absorbent cat litter with superior odor control and natural clumping properties, preferred across Europe and the Middle East.

🌾

Agriculture & Fertilizer

Used as a carrier for fertilizers, pesticides, and herbicides. Its high absorption capacity ensures controlled, slow-release delivery of nutrients to soil, improving crop yields while reducing chemical runoff.

🛢️

Oil & Gas Drilling

Processed into drilling-grade rheology modifiers for oil well drilling fluids. Sepiolite's thermal stability up to 300°C makes it uniquely suited for deep, high-temperature well environments.

🏗️

Construction Materials

Incorporated into cement, plaster, and fireproof panels. Sepiolite fibers reinforce building materials, improve fire resistance, and reduce thermal conductivity for better insulation performance.

🧪

Environmental Remediation

Deployed as an industrial spill absorbent and wastewater treatment medium. Raw sepiolite effectively captures heavy metals, oils, and organic pollutants through its extensive micropore network.

🎨

Paints, Coatings & Ceramics

Milled into fine powder for use as a rheology modifier in paints, a filler in plastics, and a binding agent in ceramic formulations. Provides thixotropic behavior and anti-settling properties.

Why Our Ore

Advantages of Turkish Sepiolite

World's Highest Purity

Turkey holds 70% of global sepiolite reserves. Our deposits consistently yield 99%+ purity grades — the highest available in the global market.

Unmatched Fiber Structure

Turkish sepiolite features longer, more uniform fiber lengths compared to Spanish or Chinese alternatives, delivering superior performance in all downstream applications.

Mine-to-Port Supply Chain

We control the full value chain from extraction to export. No middlemen, no quality gaps — just direct supply from our mines to your port of destination.

ISO-Certified Quality Control

Every batch is tested in our on-site laboratory. Full Certificate of Analysis provided, ensuring consistency across repeat orders for your production line.

Competitive Bulk Pricing

As a direct mine operator, we offer the most competitive pricing in the market. Scalable supply from a single container to full vessel loads.

Common Questions

Frequently Asked Questions

What is the minimum order quantity for raw sepiolite ore?

Our minimum order quantity is 20 metric tons, which corresponds to one standard 20-foot container. For larger volumes, we can arrange 40-foot containers or break-bulk vessel shipments depending on the destination port.

What packaging options are available for raw sepiolite ore?

Raw ore is available in 1-metric-ton jumbo bags (FIBC), or shipped loose in lined containers for maximum capacity. Custom packaging can be arranged for specific requirements. All packaging is designed to minimize moisture ingress during transit.

Can I receive a sample before placing a bulk order?

Yes, we provide complimentary samples to qualified buyers. Samples typically weigh 1–5 kg and include a Certificate of Analysis. Shipping is arranged via courier to your facility. Contact our sales team with your requirements.

What is the typical lead time from order to shipment?

Standard lead time is 7–14 business days from order confirmation, depending on volume and current stock levels. We maintain ready inventory at our warehouse and can expedite orders for urgent requirements. Transit time varies by destination.

What Incoterms do you offer for raw sepiolite shipments?

We offer FOB (Port of Mersin or Samsun Port), CIF, and CFR terms. Our logistics team handles all export documentation, customs clearance, and can coordinate shipping to any global port. We work with major shipping lines to secure competitive freight rates.
