Gilsonite (Natural Bitumen) – Low, Medium & High Ash Grades — Export from Iran
Gilsonite, also known as Natural Bitumen or Asphaltite, is a naturally occurring solid hydrocarbon resin mined from the earth. It is highly soluble in hydrocarbons, offers excellent adhesion, and provides thermal stability, making it ideal for industrial, oilfield, and manufacturing applications.
We supply premium-quality Gilsonite from trusted Iranian mines, available in Lump and Prilled forms, classified by ash content for specific industrial uses. Complies with international quality standards and suitable for bulk export to global markets.
Note: Gilsonite is classified by softening point and ash content. Lower ash = higher purity = better performance in coatings, inks, and foundry applications.
⛏️ Janis Group Gilsonite Capability: We supply premium Iranian Gilsonite (Natural Bitumen) directly from trusted mines, offering customizable ash content (<10% to >15%) and particle sizes (Lump or Prilled). Every shipment undergoes rigorous SGS inspection for softening point, ash, and solubility, ensuring reliable supply for drilling, foundry, and coating industries across Africa, Asia, and the Americas.

Applications
- Oil & Gas: Lost circulation material (LCM) in drilling muds
- Foundry: Sand additive for core molds and coatings
- Paints & Inks: Binder and gloss enhancer in industrial coatings
- Road Construction: Modifier for asphalt concrete (HMA)
- Rubber & Plastics: Filler and UV stabilizer
- Electrodes: Carbon additive in graphite electrodes
- Fuel Blending: Solid fuel additive for boilers and furnaces
Which Ash Grade Fits Your Application?
Low Ash (<10%)
Purity: Highest purity, ≥99% solubility in toluene
Choose this if: Your formulation demands maximum performance, gloss, and thermal stability without mineral interference.
Typical buyers: Ink manufacturers, industrial coating formulators, foundry specialists, and graphite electrode producers.
Medium Ash (10–15%)
Purity: Balanced performance-to-cost ratio
Choose this if: You need a reliable, cost-effective additive that still delivers strong binding and sealing properties.
Typical buyers: Oilfield drilling companies (LCM), asphalt modification plants, and road construction contractors.
High Ash (>15%)
Purity: Economical grade with higher mineral content
Choose this if: Your application is bulk industrial or fuel-based, where ultra-high solubility is not the primary requirement.
Typical buyers: Solid fuel blending facilities, heavy industrial manufacturers, and bulk construction material suppliers.
Key Notes
- Low Ash Gilsonite (<10%): High purity, used in inks, coatings, foundry, and electrodes.
- Medium Ash (10–15%): Balanced performance for drilling mud and asphalt modification.
- High Ash (>15%): Economical grade for fuel blending and industrial applications.
- Solubility: Fully soluble in toluene and aromatic solvents — excellent for formulations.
- Customization: Available in custom mesh sizes (10, 20, 30, 40, 60, 80 mesh) upon request.
- Pre-shipment inspection by SGS included for every shipment.
Frequently Asked Questions (FAQ)
Low Ash (<10%) offers highest purity for inks/coatings. Medium Ash (10-15%) is balanced for drilling muds and asphalt. High Ash (>15%) is an economical grade for fuel blending.
Lump is cost-effective if you have grinding facilities. Prilled (1-3 mm) is pre-crushed, dust-free, and ready for immediate integration into drilling mud or coating formulations.
Standard prilled size is 1–3 mm. We can customize to specific mesh requirements (10, 20, 30, 40, 60, or 80 mesh) based on your formulation needs.
Minimum order is 200 MT per shipment, packed in 25 kg PP bags or 800–1000 kg jumbo bags, loaded into 20ft or 40ft containers.
Iranian Gilsonite offers superior thermal stability, higher softening points, and excellent solubility at a significantly more cost-effective price point than most synthetic petroleum resins.
