Market Overview
Gilsonite, also known as natural asphalt or uintaite, is a carbon-rich mineral widely used in oil drilling, construction, foundries, and ink production. Among its various grades, Gilsonite with 10–15% ash content is valued for its balance of quality and affordability. Its moderate ash level makes it versatile and cost-effective, while still offering strong performance. The price per ton of this grade depends on factors such as purity, processing, and market demand.
Why Gilsonite 10–15% Ash Is Popular
This grade of Gilsonite is widely chosen because it combines purity with cost efficiency. While not as premium as the ultra-low-ash grades, it still provides excellent bonding, thermal stability, and carbon content. In addition, its availability in larger volumes makes it attractive for industries that need reliable supply at competitive costs.
Key applications include:
-
Oil and gas drilling – as a loss circulation material (LCM)
-
Asphalt and construction – for waterproofing and road durability
-
Printing inks and paints – as a natural black carbon source
-
Foundry industry – for mold additives and carbon enhancement
Factors Influencing Gilsonite 10–15% Ash Price per Ton
Several elements affect the cost of Gilsonite in this ash range:
-
Purity and ash level – lower ash grades fetch higher prices due to better performance.
-
Processing type – crushed or micronized Gilsonite costs more than raw forms.
-
Industry demand – strong demand from oil drilling and construction raises prices.
-
Origin and transport – shipping and logistics significantly influence the final cost.
Therefore, buyers must evaluate both quality and supply conditions when sourcing this material.
Price Ranges for Different Qualities of Gilsonite 10–15% Ash
1. Raw Gilsonite 10–15% Ash
Raw Gilsonite with moderate ash is widely used in asphalt and construction materials. It is the most affordable form but still delivers excellent binding and waterproofing.
Estimated Price per Ton: $250 – $400, depending on source and supply.
2. Crushed Gilsonite 10–15% Ash
Crushed Gilsonite is classified into mesh sizes for oilfield and industrial applications. It offers consistent quality and is easier to blend in drilling muds or asphalt mixtures.
Estimated Price per Ton: $350 – $550, based on particle size and packaging.
3. Micronized Gilsonite 10–15% Ash
Micronized Gilsonite is finely ground for use in inks, paints, and coatings. It provides excellent dispersion and smooth performance, making it ideal for specialized industries.
Estimated Price per Ton: $500 – $800, depending on fineness and treatment.
4. Specialty-Processed Gilsonite 10–15% Ash
This type includes chemically treated or customized Gilsonite for advanced applications. Because of its specialized nature, it is sold at premium prices.
Estimated Price per Ton: $700 – $1,000, depending on customer specifications.
Choosing the Right Gilsonite Grade
When buying Gilsonite 10–15% ash, businesses should assess:
-
Industry application – drilling, asphalt, foundry, or coatings
-
Processing level required – raw, crushed, or micronized
-
Budget balance – cost efficiency vs. performance demands
-
Supplier reliability – stable supply and consistent quality are essential
