Gilsonite

INTRODUCTION OF GILSONITE

Gilsonite History

Gilsonite was found in America prior to Samuel H. Gilson’s 1860 discovery. Gilson was not one of the primary discoverers of Gilsonite, but owing to his marketing efforts, the locals referred to this mineral by its common name, Gilsonite, rather than its scientific designation, uintaite. In 1888, he and a business partner launched the Gilsonite corporation. He extracted Gilsonite and marketed it on a commercial basis, so increasing its notoriety.

There are natural bitumen mines in the majority of oil-rich nations, except Saudi Arabia. The most significant Gilsonite mines in terms of reserves are as follows:

It encompasses the United States, Canada, Iran, Iraq, Russia, Venezuela, China, Australia, Mexico, and the Philippines. About 65 percent of the world’s reserves are found in the Americas, while Iran, the third biggest deposit, has about 15 million tons of these reserves.

What is Gilsonite?

Gilsonite is generated from crude oil that hardens and oxidizes underground over time. The surface of Gilsonite is smooth and shining, and owing to the pressure of the earth’s strata, the oil transforms into a brownish black solid.

Due to heat, this substance becomes soft and fluid. Natural bitumen is essentially the remnant of oil evaporation. In ponds surrounded by impermeable materials such as plaster, stone, etc., oil has accumulated over many years after migrating through the earth’s fissures and strata. By evaporating oil volatiles under pressure, Gilsonite precipitates and forms. Upon evaporation of oil from an oil pond or lake, a natural bitumen or asphalt lake is generated.

Gilsonite is also known by the terms

  • Mineral Bitumen
  • Asphaltum
  • Natural Asphalt
  • Natural Bitumen

The simplest description of natural bitumen is that Gilsonite (mineral bitumen) is a very pure natural hydrocarbon substance that is rich in asphaltene and nitrogen compounds. In addition to being black, glossy, and brittle, it includes sulfur and a small amount of ash. Although natural bitumen resembles hard coal or asphalt in appearance, its chemical characteristics are notably different. Gilsonite is soluble in aromatic, aliphatic, and petroleum bitumen solvents.

Currently, we provide Gilsonite in three types according to the customer’s desired application:

1- Lump Gilsonite
2- Granulated Gilsonite
3- Micronized Gilsonite Powder

Where is Gilsonite?

According to the United States Geological Survey, the states of Utah and Colorado in the United States are home to the world’s greatest deposits of natural Bitumen or Gilsonite, with an estimated 45 million tons of definite reserves.

This resource is assessed on the basis of real available natural Bitumen, since many Gilsonite mines in the globe are inaccessible owing to vein width and depth restrictions, and it is only normal that these instances are not included in the calculation of the mines’ definite reserves. For a fair comparison, it should be stated that the Gilsonite stockpile represents just 0.5% of the United States’ yearly oil output.

Saudi Arabia is an exception to the rule that natural Bitumen mines are mostly located in oil-rich nations. America, Canada, Iran, Iraq, Russia, Venezuela, China, Australia, Mexico, the Philippines, and China all have natural bitumen mines. The estimated worldwide natural bitumen reserves are around 100 million tons. Approximately 65% of the world’s Gilsonite deposits are situated on the North American continent, namely in the United States and Canada, while Iran, as the world’s third biggest natural Bitumen resource, owns approximately 15%, or 15 million tons, of these reserves. Gilsonite mines are often situated in the western region of Iran, particularly in Kermanshah, Gilangharb, Somar, Ilam, and the eastern portion of Lorestan province.

HOW IS GILSONITE EXTRACTED?

Iran Gilsonite / Iran Natural Asphalt / Iran Natural Bitumen:

The mines of western Iran (Ilam, Gilangharb, Eyvangharb, and Lorestan) are where the Petronaft Gilsonite Lump is mined, and then it is brought to the plant site to be stored there. Gilsonite lumps are poured into the hopper by the digger loader as they are broken up. After that, they are brought to the hammer mill by means of a strip conveyor. In this way, Gilsonite is divided into different grades based on the percentage of ash present and the desired size. The required tests are then completed, quality control is performed, and the product is packaged and ready to be exported in different types and grades from Iran, Turkey, and the UAE to other countries around the world.

Gilsonite applications

Gilsonite is used in over 160 significant applications in several sectors, such as paint, resin, building products, asphalt, road paving, casting, chemicals, mud and drilling cement, wax, ISO roof, black ink, and rubber. Because Gilsonite is a non-toxic mineral, the demand for this valued commodity is growing.

The principal and most significant uses of Gilsonite are as follows:

1- Gilsonite in Asphalt industry and waterproof coatings production:

Due to Gilsonite strong hydrophobicity and resistance to acid and base, it improves the quality of asphalt and coatings.

The solubility of Gilsonite materials in non-polar solvents such as carbon disulfide, toluene, and molten bitumen is an essential characteristic. This characteristic of Gilsonite is used in the waterproofing industry.

Due to the presence of polymeric hydrocarbons, natural bitumen is a good modifier for refined bitumen, particularly asphalt and waterproof coatings.

2- Gilsonite in Ink Industry and paint:

Gilsonite is harvested for its black and brown pigments, which are used to make printer ink.

Carbon black is often produced from Gilsonite resin to generate black and viscous ink.

Gilsonite resin competes very well with petroleum-based hydrocarbon resins, phenolic resins, and metal resins, and may be purchased at the same price as each of the aforementioned substances in varying quantities.

Various quantities of this substance are employed to create inks with a high degree of brilliance.

A unique kind of Gilsonite is also utilized to produce black asphalt paints and polished oils.

It may also be used to make a black-brown solution used to coat gas pipelines, sewage pipes, etc. with bitumen.

This product is used to cover exterior surfaces, as well as to make surfaces resistant to acid, as a coating for automobile chassis and metal structures.

It is a low-cost substitute for other resins in black ink formulations.

3- Isolation:

It is often used to isolate dams, bridges, and canals.

Micronized Gilsonite powder offers improved solubility and separation capabilities.

Due to Gilsonite stability and resilience to atmospheric conditions, its use in this sector is growing. In the electronics sector, it is used as an insulator in electronic kits.

4- Preparing and manufacturing emulsified bitumen:

Micronized Gilsonite powder is used in the production of aqueous bitumen emulsion.

Emulsion bitumens are recognized as eco-friendly and green bitumens.

5- Coke preparation and production:

Carbon comprises 70-80% of natural bitumen, according to elemental analyses. As a result, when added to molten steel, it provides a reducing environment and may be combined with coking elements like coal.

Bitumen is combined with coal that has poor coking characteristics to produce coke. Coke is often utilized in the sugar business.

Also, from its sulfur-free varieties or after desulfurization, needle coke, which is frequently utilized in electric arc melting furnaces, is produced.

6- Gilsonite in Drilling Muds:

Natural bitumen is used in the manufacturing of mud and cement slurry for drilling. It is used in cementing drilling fluids for oil wells.

This mineral, a unique and stabilized mixture of mineral bitumen grades, is utilized to stabilize shale in drilling mud via effective and suitable action (walls of oil wells). This ingredient decreases the slurry’s mass.

7- To prepare fuel:

In the past, lumps of Gilsonite were used as fuel in thermal furnaces alongside fuel compounds such as diesel and coal, but this application is now restricted to low-quality Gilsonite.

8-Gilsonite in Foundry Industry:

The mineral bitumen is utilized as a carbonate addition in casting sand, which makes smoother plates for gray iron molds.

Gilsonite is combined with coal sea and used as a unique adhesive for casting sand, hence reducing casting flaws.

Moreover, it facilitates mold release. Gilsonite is a binder used in casting to form metals.

In the steel industry, bitumen is mixed with chemical substances such as magnesium and hydrated lime for desulfurization.

9-Gilsonite in Other Industries, Including the Chemical Sector:

For many years, natural bitumen has been used effectively in the manufacturing of sealants and adhesives.

This product may serve as a replacement for synthetic resin in the proportion of raw materials due to its innovative manufacturing methods and exclusive natural quality control.

The usage of this natural resin in executive applications is consistent with Gilsonite excellent quality.

Investigations and specialized experiments revealed that this material is an excellent lubricant that can be combined with other resins to create a variety of goods, including pencil graphite and battery core. Also, since polyethylene or PVC materials in dark hues are eroded by the sun’s UV rays, the use of this material may avoid corrosion.

Gilsonite should be utilized in the building of the aircraft body in accordance with modern technology and the utilization of carbon fibers that may be used.

PHYSICAL PROPERTIES OF GILSONITE

In terms of its properties, Gilsonite is characterized by its high nitrogen content, which is mostly composed of pyrrole, pyridine, and amide functional groups. Additionally, there are phenolic and carbonic groups. The ratio of low oxygen to high nitrogen suggests a high output of nitrogen. This is a property of the wet surface of Gilsonite and its resistance to oxygen free radicals. Gilsonite average molecular weight is 3000 amu, which is more than that of asphalt products and synthetic resins. This may be a result of Gilsonite semi-polymeric activity as a modifying resin in polymeric and elastomeric systems. Gilsonite has a propensity for branched and adducted reactions and also interacts with formaldehyde components under certain circumstances.

Gilsonite is available in various qualities and is categorized according to its softness. The degree of softness serves as a rough guide for dissolving the adhesive and evaluating the solvent’s action. The chemical changes between Gilsonite grades are negligible, while variances in molecular weight and asphaltene/resin concentration are minimal.

Compared to manufactured goods, Gilsonite offers major health advantages:

  • Non-toxic (unlike coal and fly ash).
  • Non-carcinogenic.
  • Non-mutagenic at the genetic level.
  • Working with Gilsonite does not need strict safety precautions.

Micronized Gilsonite powder AND Granulated Gilsonite

Petronaft Co. offers Gilsonite in addition to its lump form, in granulated and powdered forms as well.

Micronized Gilsonite powder  is produced by grinding lumpy stones of natural bitumen or mineral bitumen for use in paint, rubber, industrial bitumen manufacture, and asphalt production. Micron unit (about one thousandth of a millimeter) is used to quantify this powder, which is why it is referred to as micronized powder, and micronized powder granulation is often less than 20 microns.

In the first step, the quality of micronized Gilsonite powder relies on the ground stone; in the second stage, it depends on the grain size, which varies according to micron across industries; the smaller the particles of mineral bitumen (Gilsonite), the greater the solubility of Gilsonite. As a consequence, the mixing percentage of Gilsonite powder with bitumen rises, the use of micronized Gilsonite powder decreases the baking time or mixing time of powder with bitumen, and the technique for generating bitumen with Gilsonite is simplified and optimized. During a specific procedure, Gilsonite micronized powder is changed to the necessary dimensions and used by the best micronized devices.

It is noteworthy to note that Gilsonite micronized powder is naturally non-toxic and harmless to the body. Among the notable properties and characteristics of this material are the following:

  • Working with Gilsonite does not need strict safety precautions.
  • No toxin.
  • No carcinogenic properties.
  • Compliance with EPA drilling regulations.
  • Absence of genetic mutation.

At this time, PETRO NAFT is manufacturing a variety of grades of gilsonite, including the following:

1- Gilsonite with ash content up to 5%, moisture up to 1% and meshes 30, 40, 100 to 300.

2- Gilsonite with ash content up to 10%, moisture up to 1% and meshes 30, 40, 100 to 300.

3- Gilsonite with ash content up to 15%, moisture up to 1% and meshes 30, 40, 100 to 300.

4- Gilsonite with ash content up to 20%, moisture up to 1% and meshes 30, 40, 100 to 300.

5- Gilsonite with ash content up to 25%, moisture up to 1% and meshes 30, 40, 100 to 300.

Because our plant is mechanized, we are able to supply Gilsonite with mesh sizes ranging from 100 to 300, which are highly crucial for certain applications.

Gilsonite price

The price of Gilsonite is determined by several variables, including:

– Seasons: During the winter, when the quantity of precipitation is large, the mines are filled with rainwater; as a consequence, the market experiences a scarcity and the price rises. From March through October, then, Gilsonite is offered at its lowest price.

– Demand Quantity: Sometimes huge mines need additional digging and trash collection. If demand is strong at that period, the price will change.

– Quality: In each mine, there is a thick layer of natural asphalt, and the proportion of Gilsonite in each layer varies in quality.

In certain areas, natural asphalt is of impeccable grade. In Middle Eastern mines, the proportion of Gilsonite ash ranges from 0 to 25%.

The most popular kind of natural asphalt is typically natural asphalt with 5 to 15 percent ash.

Frequently Asked Questions About GILSONITE

When compared to asphalt emulsion, our Gilsonite Sealer's characteristics are similar, but it is superior at penetrating asphalt for optimal rejuvenation because of its solvent-based oil asphalt sealcoat sealer formulation. Gilsonite sealers can be used for general sealcoating, although its intended use is to repair asphalt that has been damaged by weather or ultraviolet light.

 

According to their five distinct sources, natural bitumens or Gilsonites are classed appropriately.

1- Bitumens accompanied by layers and other substances in which oil is created.

2- On the ground, the bitumens that accompany the hemiclonal layers and the ends of the aforementioned margins are apparent.

3- Bitumens found at discontinuities and other slopes.

4- Bitumens produced by vast reservoirs that have been fractured by processes like as bending and faulting.

5- Bitumen detected concurrently with the incursion of certain geological events, including volcanic eruptions, salt domes, and igneous intrusions.

The chemical changes between Gilsonite grades are negligible, while variances in molecular weight and asphaltene/resin concentration are minimal.

 

The mineral now known as "Gilsonite" or Asphaltum was found in the early 1860s, but it was not until the 1880s that Samuel H. Gilson started marketing it as a waterproof coating for wooden posts, as Cable wire insulation, and as a unique lacquer. Gilson's introduction of bitumen was so successful that he and a partner founded the first corporation to extract and sell it commercially in 1888. Gilsonite was selected due to its superior purity, high solubility, and use in the paint and varnish industries. The bitumen mineral has a high softening point and a recognized hydrocarbon structure.

The extraction and categorization of bitumen, as well as the classification system, have been continuously modified by the passage of time and technological advancements. Now, industrial or mine processing eliminates the majority of inert impurities and generates newer, more potent solvents with greater degrees of softening for a range of uses. Today, Gilsonite is categorized according to its softening point and particle size. All sorts of mineral bitumen grades are of far greater quality than the initial few samples that were introduced to the market in the 1880s.

Production techniques:

Gilsonite or Asphaltum is a natural hydrocarbon with a structure similar to resin that was discovered in 1930 in the south of Turkey. This natural asphaltite is a brittle hydrocarbon that is often referred to as natural asphalt, asphaltite, unity, or asphalt.

Gilsonite is soluble in aromatic, aliphatic, and petroleum bitumen solvents. Primarily, Gilsonite is used to harden softer petroleum products.

Gilsonite is a glossy, black material that resembles the crystal obsidian in appearance. This material is fragile and readily transforms into a dark brown powder upon crushing.

The mineral Gilsonite is often found in veins or seams that are two to six feet broad, but may reach widths of up to 28 feet. The veins are almost perpendicular to one another and run from northwest to southeast.

The length of these veins is many kilometers, and their maximum depth is around 500 meters. This material's veins appear as a thin protrusion on the surface and progressively increase as they descend. Typically, pneumatic cutting hammers and mechanical lifts are used to extract veins with a smaller width. However, for veins with a larger depth, mining equipment are required.

 

Gilsonite, often known as natural asphalt, is a black, viscous, mineral material whose structure consists of dissolved solid hydrocarbons. Bitumen is often discovered in mines. This solid mineral has a relatively high melting point, and its primary sources are in the U.S. states of Colorado and Utah. Recent discoveries in countries such as Colombia and Iran have led to the extraction of a substantial quantity of this material. Although the primary sources of the mineral Bitumen are in the American area, additional sources have recently been identified in countries such as Colombia and Iran.

Gilsonite, or the mineral Bitumen, collected from subterranean mines, resembles obsidian in look and color. In around 25 years after its discovery in the 1860s, Samuel Gilson commercialized this substance as a varnish, electrical insulator, and waterproof compound.

 

Gilsonite deposits are dispersed globally, particularly in oil basins. Mineral bitumen is used in over 160 industrial goods, especially in the manufacturing of printing inks and dark colors, oil well drilling cements, asphalt modifiers, sand additives and foundry sand, as well as a vast array of crops.

1- The usage of Gilsonite in bitumen production:

Gilsonite is often used in the composition of bitumen. This practice is prevalent in nations such as China, India, and Iran. We are all aware with the use of bitumen for insulating buildings.

2- Utilization of bitumen in the ink and printing industries:

Gilsonite is an essential component in printing inks, paints, and industrial coatings. In a sort of coating, Gilsonite is employed as a hard resin and carbon black spreading ingredient. Formulas for creating various kinds of printing inks and industrial coatings vary. Different amounts of bitumen are used in various products. The original formulation of a product is determined by the product's quality and intended use.

The original formulation of a product is determined by the product's quality and intended use.

3- Use of Gilsonite in road building and asphalt paving:

For road building and other construction projects, bitumen and asphalt are combined to provide a more durable texture. This approach utilizes bitumen in the form of granulated powder. In some situations, modifying polymers are substituted for this mixture.

In terms of physical and functional properties, asphalts made with Gilsonite are superior to those made with standard asphalt. The structure of asphalts reinforced with mineral bitumen is more robust and resistant to water and shape change. These asphalts are well suited for high-traffic or high-pressure highways and routes.

4- Gilsonite applications in drilling mud:

With drilling mud, Gilsonite is combined. This activity reduces the erosion of the well's walls, which facilitates the drilling procedure.

5- Use of mineral bitumen in the foundry industry:

Bitumen is used as a carbon-rich ingredient in foundry sands because to its hydrocarbon structure. Thus, at the conclusion of casting and molding, the processing procedures are flawlessly accomplished.

This property is also used in the steel and iron smelting industries. The presence of mineral bitumen in the structure of steel melt, sulfur, silica, and phosphorus impurities must be segregated to the slag side of the combination.

6- Applications of Gilsonite in anti-corrosion coating production:

In the oil and gas business, Gilsonite is used in the development of anti-corrosion coatings, which is another significant application of this mineral. This material, together with other additives, is employed in the texture of coatings and for the insulation of oil, gas, and petrochemical pipelines.

 

Gilsonite is categorized as a material that is soluble in oil solutions, such as trichloroethylene. This material constitutes the majority of Gilsonite carbon. It also includes a number of other elements, including nitrogen and sulfur, as well as volatile chemicals. Asphaltite is a hard and solid mineral composed of various natural bitumens whose principal constituents, asphaltenes, have very large molecule sizes.

Asphaltite is dark brown to black in hue. They are insoluble in a solution of naphtha, one of the petroleum derivatives, and so need heat to liberate their petroleum content. Despite the fact that Gilsonite is linked to asphalt, asphaltite is chemically and physically distinct from it. For instance, asphaltites often include few or no minerals, while asphalts may contain a rather significant proportion of these substances. Additionally, unlike asphalt, asphaltites do not readily boil.

In terms of specific weight and softening temperature, asphaltites vary significantly amongst one another. Gilsonite is soluble in solvents containing cyclic hydrocarbons, aromatic solvents, and chlorine. This chemical is insoluble in the majority of ketones; however, it is soluble in mixed aromatic solvents with an organic component. Gilsonite is insoluble in alcohol, acetone, and water.

      • High levels of strength and endurance.
      • Outstanding performance in terms of deformation.
      • The pavement’s depth has been reduced.
      • Cold temperature resistance has enhanced.
      • Superior resistance to the eroding impacts of water.
      • Gilsonite contributes to the durability of roadways, allowing them to be utilized for extended periods of time.
      • Making longer-lasting pavement is good for the environment. Restoring pavements using recycled asphalt rather than totally replacing them has been demonstrated to result in a significant reduction in both the quantity of energy utilized and the number of resources required.
      • Natural antioxidant.
      • It revitalizes the pavement.
      • It has strong adhesive properties.
      • Outstanding fading resistance and overall appearance.

  2. I read somewhere that gilsonite has a meteorite origin ( gilsonite meteorite ), is this true?

    1. Thank you for your comment.
      Gilsonite does not actually have a meteorite origin.
      Gilsonite is created by hardening and oxidizing crude oil underground over time. The surface of Gilsonite is smooth and shiny, and the oil turns into a brownish black solid due to the pressure of the earth’s layers. Heat causes this material to soften and flow. Natural bitumen is the byproduct of oil evaporation. Oil has collected over many years in ponds surrounded by impermeable materials such as plaster, stone, and so on after migrating through the earth’s cracks and layers. Gilsonite is formed by evaporating oil volatiles under pressure. A natural bitumen or asphalt lake is formed by the evaporation of oil from an oil pond or lake.

    1. Thank you for your good question
      Yes, Gilsonite is used to protect pipes from corrosion and also as an additive in pipe isolators, both of which contribute significantly to pipe life extension. Gilsonite is a kind of resin that may be used to waterproof objects in a variety of different industries.

    1. Hello,
      Your comment is appreciated.
      Pavement sealer is a Seal Coating compound that is used for driveway sealer. Sealer is a liquid coating that protects the surface. Pavement Sealer is applied to the surface of asphalt pavements to preserve them against environmental deterioration. Gilsonite may be used to create asphalt pavement sealers as a raw ingredient liquidized into a bituminous soft substance in a suspension mix. Gilsonite Sealer has unique properties that allow strong binding with the asphalt bituminous component and crucial protection against cracking, particularly during the freeze/thaw cycle.

  7. Hello;
    We are gilsonite supplier for drilling companies in Indonesia, as you know the depth of wells in Indonesia is very high and therefore there is very high heat, can you provide gilsonite with high temperature application?

    1. Hello,
      We are happy to meet you.
      Yes, apart from the standard types and grades, we optimize Gilsonite according to the customer’s needs, and we can also provide Gilsonite for deep wells with high temperatures.

  8. Hello and greetings
    Can Gilsonite be used to reduce steel impurities in the production process?

    1. Yes, this is one of the uses of gilsonite in the steel industry, we will provide you with a more complete explanation below:
      Gilsonite is a component of various additives used in the steel making process. It is used as an ingredient in the production of limestone, lime, magnesium, and calcium carbide. These additives remove impurities from the liquid steel, such as sulfur, silica, and phosphorus, and transfer them to the still-liquid layer of liquid slag. Gilsonite, as a component of Steel Making Additives, is responsible for a variety of duties. When applied to molten steel, Gilsonite promotes additive mixing, allowing chemical processes to occur that transport impurities to the molten slag layer. First, at 1900°F, Gilsonite is roughly 75% volatile. It enhances the mixing of the additives when put to steel. Following that, the volatiles emitted include a substantial quantity of lustrous carbon, which further lowers the iron oxide to steel. Even though CO is responsible for the great majority of the indirect reduction of Fe3+, some of it must still be reduced directly by elemental carbon. Finally, the component of Gilsonite that does not volatilize is a highly ordered asphaltene structure that is nearly totally made of carbon. This increases the quantity of carbon in the steel.

    1. As a raw material, gilsonite may be used to create asphalt pavement sealant, which can then be processed into fine bituminous material in a sludge combination.
      • Gilsonite Sealer has unique qualities that allow excellent adherence to bituminous surfaces.
      • Sealers prevent against cracking, which is particularly important during freeze/thaw cycles.
      • The qualities of gilsonite guarantee the longevity of asphalt and emulsion coatings.
      • Gilsonite Sealer’s nature regenerates the molecular connections in the paver surface and assists in color effects, resulting in a sharp, glossy black look.
      • Gilsonite Sealer is commonly utilized in driveways, streets, and roads, as well as heavy traffic roadways such as highways, due to its unique qualities.
      • Gilsonite Sealing Coating has been found to increase the life of pavement by up to 25 years when applied every one to two years.
      • Gilsonite may also be used to make fresh asphalt by combining it with asphalt paving debris.

  9. Hello all
    Is it possible to manufacture tires for heavy vehicles with Gilsonite?

    1. Thank you for your comment
      Yes, one of the main uses of Gilsonite in the industry is in the tire industry, When combined with carbon black in the manufacturing of rubber, the inclusion of gilsonite, also known as natural asphalt, results in a significantly more reinforced substance. This is due to the fact that gilsonite facilitates the absorption of carbon black into natural rubber when it is combined with the other components. Because of its high carbon content, gilsonite performs well in circumstances where carbon black is utilized in hot mixtures. Furthermore, due of gilsonite’s unique features, the resultant rubber will have greater abrasion wear strengths, making it perfect for usage in the tire industry. Natural asphalt serves as the optimum binder when utilized in the creation of synthetic rubber or in combinations including natural rubber, offering greater results at a cheaper cost than alternative adhesive solutions.
