In addition, there are several different types and ranks of Gilsonite and gilsonite powder. Furthermore Natural asphalt is classified by degrees of hardness, moisture and softening point. Powder gilsonite also is hard petroleum, almost hydrocarbon, and containing the highest fuel content. Bituminous rock is a type of Gilsonite , the most common type in Iran, used to mix with oil base products to modify bitumen and to make high quality bitumen for high way and Airports also special Iran Gilsonite(mineral bitumen) using for fluid lose control and stabilizing hole shale.
Gilsonite Powder uses:
- drilling fluid
- oil and gas
- asphalt and road paving
- paint and ink industry
- water proofing
- pipe coating
Natural Bitumen Source:
Gilsonite is founds in vertical veins with 2-6 feet in width. Also can be as wide as 28 feet. Veins are nearly parallel to each other. They extend many miles in length and as deep as 1500 feet. In addition, veins will show up on the surface as a thin outcropping and gradually widen as it goes deeper. The primary difference is that modern miners use pneumatic chipping hammers and mechanical hoists.
natural asphalt is included in a class of solid bitumens known as asphaltites. Gilsonite deposits are located inGilan e Gharb, Kermanshah, Iran. They are different from other asphaltites because of their high:
– asphaltene content
-solubility in organic solvents
-purity and consistent properties
pub-ltd gilsonite powder are categorize with different ash contents includes: 5%, 5-10%, 10-15% also <20%. This grades are uses in different industries according the spec.
Gilsonite also in its unaltered state is non-carcinogenic, non- mutagenic, and non-toxic by recognized test procedures, which include the modified Ames assay test, chronic feeding studies for the National Toxicology Program (NTP), and NIOSH protocols.
Processing of Gilsonite also now removes most of inert contaminants and newer, more powerful, solvents make the higher softening point grades more interesting to the user. Gilsonite grad by softening point and mesh size. In addition, all grades carry a degree of quality far superior to those first small amounts of crude Gilsonite marketed in the 1880s. Our grade of Gilsonite is finely powdered. Its softening point is 130–204 °C (265–400 °F).
Natural Bitumen chemical properties:
This unique mineral is used in more than 160 products, primarily in dark-colored printing inks and paints, oil well drilling muds and cements, asphalt modifiers, foundry sands additives and a wide variety of chemical products. Gilsonite is shiny, black substance similar in appearance to the mineral obsidian. Gilsonite also can crushed to dark-brown powder. Configuration of bitumen`s internal structure determined by chemical constitution of molecular type present.
In addition, its a complex chemical mixture of molecules of a predominantly hydrocarbon nature with a minor amount of structurally analogous heterocyclic species and functional groups containing sulfur, nitrogen and oxygen atoms. Bitumen also contains trace quantities of metals such as vanadium, nickel, iron, magnesium and calcium which occur in the form of inorganic slats and oxides or porphyrine statures
