Iran Gilsonite Lump
Gilsonite lump with ash percentage between 0 and 25
Gilsonite, or Natural Asphalt , Natural Bitumen is a natural, resinous hydrocarbon This natural asphalt is similar to a hard petroleum asphalt and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. Natural asphalt is derived from the natural mutation of petroleum. This mutation happened a million years again under the influence of bacteria. This bacterial decomposition of petroleum resulted in reduce content of saturated hydrocarbons, mainly n-alkalenes and light oil which became heavier and more viscous , taking the form of asphalt. It is natural product a bituminous limestone in which carbonate of lime and pure natural asphalt are most intimately combined by natural agency. It is as bitumen created in the process of crude oil processing. It is native substances of variable color, hardness and volatility, composed principally of the elements carbon and hydrogen and sometimes associated with mineral matter and essentially free of gas. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, gilsonite is frequently used to harden softer petroleum products. Gilsonite in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder. Gilsonite is found below the earth’s surface in vertical veins or seams that are generally between two and six feet in width, but can be as wide as 28 feet.
Due to the narrow mining face, Gilsonite is mined today, much like it was
50 or 100 years ago. The primary difference is that modern miners use pneumatic chipping hammers and mechanical hoists.
Packaging
(One metric ton) new jumbo bags.
These Products can be palletized, shrinked and wrapped according to customer’s request.
RAHA Gilsonite Company owns a plant located in Kermanshah with the full automatic progressive machinery for processing and packaging Gilsonite in 3 separate production lines. Hence we have the honor to render our high services to our valued customers.
Lump Gilsonite production line
We are equipped to separate the sands from Gilsonite pile which are conveyed from the mine to the plant and make grading according to customer’s satisfaction.
RAHA Gilsonite lump is extracted from Western Iranian mines (Ilam, Gilangharb, Eyvangharb, and Lorestan) and are accumulated in company site. Lumps are spilled into the hopper by digging loader. Then, they are transported to hammer mill by strip conveyor.
