People know bitumen by different names in the world. In the United States, for example, it is commonly called asphalt. As you know, bitumen is a dense hydrocarbon derived from oil.
Bitumen is black and sticky and comes in two forms:
  • Natural bitumen

  • Refined bitumen from crude oil in refineries

Natural bitumen :

When crude oil comes to the surface over millions of years , it appears as solid or semi-solid veins on the surface .

it exists in two forms in nature:

  • Lake bitumen ( such as Trinidad bitumen lake in American continent )
  • Mineral Bitumen or gilsonite ( located in the western mountains of Iran in Kermanshah )

what is gilsonite ?

gilsonite  or natural asphalt also known as  uintahite , asphaltum or asphaltite . it is a solid, black, and glossy material composed of large amounts of carbon and hydrogen .  with minor ratios of sulfur, nitrogen and oxygen . Research has shown that natural asphalt is of better quality than other types of bitumen. It is also known as an amazing mineral due to its gilsonite uses .

gilsonite applications are so diverse that it has made this amazing mineral popular.

How is Gilsonite underground?

In the mines of the Middle East natural asphalt is found beneath the earth’s surface in the form of vertical veins . it is usually two meters to eight meters wide. These veins are also parallel and are usually elongated. These veins appear partially on the earth’s surface, which reaches the extraction stage after expertise and study. the greater the extraction, the more traces of Gilsonite appear, indicating that the area is rich in Gilsonite . It seems that natural asphalt streaks under the mountains be tens of kilometers in some areas.

The popularity of Gilsonite

As is clear  natural asphalt  is a popular raw material due to its many applications in industry. Every year, many investors around the world buy this important mineral and get a lot of products by processing it . Factory managers believe that Gilsonite has improved product performance. It can also be a better alternative fuel. that is also well adapted to the environment. Researchers have been studying the properties of natural asphalt in industry for several years . If they do more research on Gilsonite, they will discover more applications. Today, engineers use Gilsonite powder in ink and paint and control fluid in drilling.

History of gilsonite :

In the early 1860s, no one knew about natural asphalt and its applications. Until a man named Samuel H. Gilson discovered the product as an amazing substance and began to promote it . he believed that it is a good insulator for wooden wires and sidewalks. Because it prevents water from penetrating . that is environmentally friendly and washable for wooden sidewalks. His idea was a successful .  he and his partner finally formed the first company to extracting and selling natural asphalt on a large scale. So that everyone knew that as Gilsonite.

Chevron also embarked on a major breakthrough . They set up a company to explore more applications and find a global market for the product.

Where is Gilsonite found?

In some parts of the world you can find a few mines of Gilsonite . but generally originate from the states of Utah and Colorado in the United States and Kermanshah and Ilam in Iran.
Also, due to high demand for natural asphalt , it is widely extracted in the Middle East . that is makes Iranian Gilsonite affordable.
