Natural bitumen is a broad name for bituminous materials that occur in geological deposits. Their composition and physical form vary by source: some are viscous, while others are solid and brittle. The term should not be confused with petroleum bitumen made by refining crude oil, or with the finished asphalt mixture used to pave roads. Gilsonite is one commercially important solid natural bitumen.
What is natural bitumen?
Natural bitumen contains complex hydrocarbons and may also contain mineral matter and smaller amounts of sulfur, nitrogen and oxygen compounds. Its properties depend on the deposit and processing. Buyers should therefore compare measured characteristics such as ash content, softening behavior, moisture, solubility and particle size instead of assuming that every natural bitumen has the same performance.
Is Gilsonite the same as natural bitumen?
Gilsonite is a type of naturally occurring solid bitumen, often classed as an asphaltite. Natural bitumen is the wider category; the terms are not interchangeable for every deposit or product. Gilsonite is mined and supplied as lumps or processed into powder for industrial formulations. Learn about Asia Gilsonite and its supply options, review the powder and mesh guide, or compare grades and specifications.
To separate geological origin from commercial supply, see how Gilsonite is formed, where Gilsonite deposits are found, and our production and processing profile.
The U.S. Geological Survey describes Gilsonite as an asphaltite and documents its historical uses in paving materials, inks and oil-well products. See its geological report on Gilsonite. Source-specific laboratory results remain necessary when choosing material for a formulation.
Natural bitumen, petroleum bitumen and road asphalt
Natural bitumen occurs in the earth. Petroleum bitumen is generally obtained during crude-oil refining. In road construction, asphalt usually means a mixture of aggregates and a bituminous binder. Usage of the words asphalt and bitumen differs across regions, so procurement documents should specify the material, grade and test method rather than rely on the name alone. See whether Gilsonite is asphalt for the terminology and pavement-use distinction, and review the Bitumen vs Gilsonite comparison for procurement differences.
Where is natural bitumen used?
Depending on its properties and the formulation, natural bitumen can be used in road binders, waterproofing, coatings and other industrial products. Gilsonite has more specific uses as an additive in asphalt paving, drilling fluids, paint and ink, and foundry formulations. Each application needs a suitable grade; the Gilsonite applications hub links to the detailed pages.
How is natural bitumen priced?
There is no single price for all natural bitumen. Product type, ash and other quality limits, form or mesh, packing, order size and delivery terms affect a quotation. For Gilsonite purchasing, see the Gilsonite price per ton page and the bulk buying guide. A useful inquiry should include the intended application, required specification, quantity and destination.
Is natural bitumen renewable?
No. Natural bitumen forms through geological processes over very long periods and should be treated as a finite resource. Environmental claims about one material or formulation require specific lifecycle evidence; a natural origin alone does not establish a lower carbon footprint.
