Natural Bitumen: What is gilsonite bitumen + advantages!

Natural bitumen, mineral bitumen or Gilsonite is a natural resinous hydrocarbon. This bitumen is similar to hard petroleum asphalt and is classified by geologists as a substance soluble in petroleum solvents. In this article, we will talk more about natural mineral bitumen, Gilsonite applications, Gilsonite mine in Iran, global natural bitumen price, and what mineral bitumen is.

What is Gilsonite or natural bitumen?

Gilsonite, or natural bitumen, is a stone impregnated with bitumen (asphaltite), which is solid. There are natural bitumen mines in different countries like America and Iran. The mines in Iran are mostly located in Kermanshah province. Mineral bitumen has a relatively high melting temperature and is used primarily as electrical insulation or waterproof compounds.

What is Gilsonite or natural bitumen?

Gilsonite powder

Gilsonite is widely available in Iran, and Iran is known as the largest hub for buying and selling natural bitumen.

Gilsonite powder, or natural bitumen powder, is a solid hydrocarbon material extracted from the compression of organic materials over millions of years. Natural gilsonite is dark brown to black and shiny, and can be easily ground into powder. Gilsonite’s chemical formula consists of complex hydrocarbons and a small amount of nitrogen, oxygen, and sulfur.

Natural gilsonite powder dissolves in aromatic and organic solvents easily, and because of this property, it usually has uses as an additive in various products. Gilsonite and its powder are obtained from 100% natural sources, which makes it environmentally friendly.

How are natural bitumen reserves formed?

They were deposited in the mud of the bottom of the ocean or a lake where living organisms lived. Under the heat of over 50 degrees Celsius and the pressure of burial in the deep earth, they turned into substances such as bitumen, kerosene or oil.

Most of the bitumen used commercially obtaines from crude oil, but there are also large amounts of bitumen in nature. Natural bitumen is formed from the remains of algae, diatoms and other organisms. These deposits of mineral bitumen were formed in the Carboniferous period, when there were vast swamp forests in many parts of the earth.

Discovery of Gilsonite

Gilsonite, or natural bitumen, was first discovered in America in the 19th century. Samuel H. Gilson discovered this material first. He discovered a shiny, black crude substance that was found to be more than 95 percent hydrocarbons.

Over the years, Gilson made many attempts to use this material for various applications but was unsuccessful. In the following years, natural bitumen from the mine was used for other applications. For example, Gilsonite has been used in the paint and varnish industries – due to its better purity, solubility and applicability. This mineral bitumen had a high softening point, and its hydrocarbon structure was familiar to people active in this business.
