Definition of Gilsonite

Gilsonite, also known as uintaite, is a naturally occurring hydrocarbon resin that is mined in the Uinta Basin in Utah, USA. It is a black, shiny, and brittle material that is composed of a complex mixture of hydrocarbons, including aromatic and aliphatic compounds.

Brief History of Gilsonite

Gilsonite has a long and interesting history that dates back to the late 19th century. It was discovered in the Uinta Basin of Utah, USA, in 1888 by Samuel H. Gilson, a mining engineer who was searching for silver and gold deposits in the area. Instead, he stumbled upon a strange, shiny black substance that he initially thought was a type of coal.

Importance of Gilsonite

Gilsonite is widely used in the drilling industry as an additive to drilling fluids. It helps to improve the lubrication and stability of the fluid, reduce fluid loss, and enhance the ability of the fluid to carry cuttings to the surface. This leads to more productive and cost-effective drilling operations.

Composition of Gilsonite

A chemical composition of Gilsonite has about 85% carbon, 10% hydrogen, 1.5% oxygen, 0.3% sulfur, and 0.2% other elements, while its carbon contents has made up of 68.3% aliphatic carbon and 31.7% non-aliphatic carbons.

  • Chemical Properties of Gilsonite

Low hydrogen to carbon atomic ratio (1.44), low sulfur (0.27 wt.%) and high nitrogen (3.25 wt.%) contents were the main characteristics of the Gilsonite.

Types of Gilsonite

  • Natural Gilsonite

Gilsonite is a naturally occurring, solid, black, lightweight organic material that originates from the solidification of petroleum.

  • Hard and Soft Gilsonite

Gilsonite is hard hydrocarbon and while adding and mixing with other softer material the finish product become more harder and tough.

  • Processed Gilsonite

By blending Gilsonite to other aromatic oil and heat it up the process and hemogenic will start and finished product would be under control such as softening point and penetration.

  1. Powdered Gilsonite:
    Gilsonite is brittle and easy micronize starting from 10 mesh to 400 mesh but most common size specially for oil well drilling mud in 200 mesh.We are packing the powder in bag and jumbo bag to export to other countries
  2. Pelletized Gilsonite:
    DOP oil and Gilsonite powder along with polymer and PVC mix together in special media and fully melt and make Gilsonite pellet.

Production and Processing of Gilsonite

  • Mining Gilsonite

There are two types of mining Gilsonite, one type is underground which the capacity is small but quality is high and mining would be in core side but other type is open system and by excavator and daily till 1000MT can take out the material.

  • Processing of Gilsonit

A process for the production of a gilsonite like bituminous material having a penetration of 0 to 1 and a softening point of 130c to 180c Which comprises solvent extracting a material selected from the group consisting of straight asphalt and the vacuum distillation residue obtained in the production of lubricating oils to obtain a material having a penetration of 2 to 30, and then air blowing said material having a penetration of 2 to 30 at a temperature of 200 to 300c.

  • Crushing and Grinding

Depending on the method of grinding, Gilsonite can be made in different mesh sizes, starting from 30 to 300 for Simple crushing machinery.while you need to make more than 100 need to do the crushing in three to 5 steps.

  • Solvent Extraction

If you heat up Gilsonite and condense the smokes it will become liquid and raw solvent will collect which has several types of light and heavy aliphatic and aromatic hydrocarbon on.

How is Gilsonite mined?

Exploration and site preparation: The first step in mining Gilsonite is to identify potential deposits and conduct geological surveys to assess their size and quality. Once a deposit is identified, the site is prepared for mining by clearing vegetation and constructing access roads and infrastructure.

Drilling and blasting: In underground mining, tunnels are drilled into the deposit using drilling equipment, and explosives are used to create openings for extraction. In open-pit mining, the overlying rock and soil are removed using explosives and heavy machinery.

Extraction and processing: After the deposit has been opened, the Gilsonite is extracted from the rock using mining equipment such as front-end loaders and conveyor belts. The extracted material is then transported to a processing plant, where it is crushed, screened, and purified to remove impurities.

What are the health benefits of Gilsonite?

There is limited scientific evidence to support the health benefits of Gilsonite in humans. While Gilsonite is used in some traditional medicine practices, more research is needed to understand its potential health effects.

However, Gilsonite is known to contain a variety of minerals and trace elements, including zinc, iron, magnesium, and calcium, which may have beneficial effects on overall health when consumed as part of a balanced diet.

In addition, Gilsonite is sometimes used as a dietary supplement due to its high content of humic acids, which are natural organic compounds that may have antioxidant and anti-inflammatory properties. Some studies have suggested that humic acids may have potential health benefits, such as improving immune function and reducing inflammation, although more research is needed to confirm these effects.

It is important to note that Gilsonite should only be consumed in small quantities as a dietary supplement, as excessive intake may lead to digestive problems or interfere with the absorption of certain nutrients. As with any dietary supplement, it is recommended to consult with a healthcare professional before adding Gilsonite to your diet.
