Due to the complexity in refining mineral products, gilsonite as a natural asphalt is very similar to the material obsidian. Therefore, consultancy on mineral asphalt and bitumen products is highly recommended.
Natural Asphalt sources
Gilsonite is a resinous and natural hydrocarbon. This material is very similar to petroleum hard asphalt and is often referred to as natural asphalt. Other common names for this material are asphalt, unatite, and asphalt. Like natural asphalt, gilsonite is soluble in asphalt and aromatic solvents. Due to its high compatibility, gilsonite is often used to harden softer petroleum derivatives. Gilsonite is a lustrous, black material very similar to cratered obsidian. It is very crunchy and easily turns into a dark brown powder. Gilsonite, "Natural asphalt, Natural Bitumen "in general have been classified by Abraham on the based-on animal, vegetable and mineral. It is solid asphalt resembling coal very much in appearance. Gilsonite, "Natural asphalt, Natural Bitumen" has two types of molecules, a straight carbon and a ringed carbon. When you heat the Gilsonite, "Natural asphalt, Natural Bitumen" the two components separate. The ringed carbon vaporizes and is called a volatile. A straight carbon remains and becomes the residue, or sometimes called carbon or carbon black. We are exporting the carbon in the residue form. The volatile after cooling done can be used as a fuel and fuel should be refined to segregate sulfur or other elements and add additives. Gilsonite occurs underground in vertical strata. It is usually found to be two to six feet across, but as wide as 28 feet have been seen. The strata are completely parallel to each other and trend northwest-southeast. The layers are miles long and 1,500 feet deep. The layers are such that the deeper we go into the surface, the width of the layers increases as we go deeper into the surface. Today, due to the narrow mining frontage, gilsonite is mined using bulldozers, loaders and hammers, and other new mechanical equipment. Gilsonite applications Oilfield: Gilsonite is used as a mud drill when drilling oil wells.

Asphalt and Paving Sector: Gilsonite acts as a performance quality improver in the asphalt mix. Asphalt modified with Gilsonite has a higher pg and is easy to mix with asphalt mixtures without the need for high rolling force unlike other modifiers and emulsion base It is also suitable for the production of various insulators which have better texture and wear resistance Natural bitumen is made from crude oil, which is formed by the slow spontaneous evaporation of light and medium components and their polymerization and oxidation. Natural bitumen can be obtained by boiling it in pots or by dissolving it in organic solvents. This species does not occur in nature, but always exists in nature as a mixture with various mineral substances called asphalt, the percentage of bitumen in it varies, and in the purest type of natural asphalt, which is subject to the common name gilsonite, It is found that about 9 percent contains bitumen. Natural bitumens are heavy hydrocarbon materials and are divided into different groups based on their formation, physical properties, solubility in cs2 carbon tetrachloride and chemical composition, such as branches. For example, asphalts are divided into gilsonite, grahamite, bright pitch groups, and the gilsonite group is the best and most well-known natural bitumen group. This material exists in liquid, semi-solid, and solid physical states depending on the purity percentage and age, etc. and different in cs2 solvent - with different solubilities, and some types of it can be used directly, and some of these types of bitumen should be processed or used in mixtures with petroleum bitumen. Natural bitumen is made from crude oil, which is processed into natural cotton after the gradual evaporation of smaller substances and through processes such as oxidation, sulphuration, polymerization and condensation under the influence of time and three factors, heat and pressure. As a result, the quality of natural bitumen varies depending on the type of reactions carried out and the duration of the reactions (lifetime of natural bitumen), so that natural bitumen has liquid, semi-solid and solid states of aggregation and different chemical properties. - Natural bitumen of relatively pure nature: This category can be considered as one of the most important types of natural bitumen. They are usually found in liquid and semi-solid forms with ponds containing less than 10% minerals and being relatively more volatile. Samples of this type of natural bitumen, for which the exact number of mineral reserves is not available, are found in the Khuzestan province.
Natural Asphalt meaning
They usually have a low melting point and their degree of penetration varies from 0. 1 mm to very soft 10 . Their volatile content ranges from less than 7% for 5 hours to 20% for 5 hours. Their solubility in cs2 generally exceeds 90% and the amounts of c, h, n and s are about 82, 11, 2 and 2% by weight respectively - Asphalt pyropitums: This category of natural bitumen mostly of high melting point or non-melting point, including various groups such as elaterite, wurtzilite, albertite and impenitent. Most of the natural bitumens found in the west and south-west of the country are asphalt pyrobitum and albertite, imzonite branches. Apart from being insoluble, they have a long lifetime and increase their solubility in cs2 solvents. The export of natural bitumen to Iran is not booming at present for many reasons such as: B. the presence of highly aged Balerial sulfur, a high percentage of its associated minerals and the lack of precise identification of the natural bitumen type Use of natural bitumen in road construction One of the factors that play an important role in the life and durability of an asphalt mixture is the quality of the bitumen used. For example, if the bitumen used does not adhere properly to the mineral aggregate surface, especially near water, the aggregate will flow and the road surface will be destroyed. Various additives have been proposed to improve bitumen quality and viscosity, including natural bitumen. The research results of the Oil Industry Research Institute showed that adding bitumen to oil pits would improve the quality of Oil Cola in the following aspects. - Increases the adhesion of bitumen to minerals in the presence of water: The presence of some adherent materials in natural coal significantly increases the adhesion of petroleum bitumen. Experiments conducted at the Oil Industry Research Institute have shown that natural types of bitumen (depending on their quality and composition) increase the adhesion of petroleum bitumen to mineral content (in the presence of water) more than twofold.
