Gilsonite analysis
Iran Gilsonite analysis and specification is variable depend on mine and location of the Gilsonite Zone. Normally if you explore from core of Gilsonite mine there is less impurity in gilsonite but when you take from beside of mine there are too much impurity and soil including the mineral bitumen and it should be separated before pulverizing to powder.
The impurities will effect to quality and specification of goods and damage properties of Gilsonite.
Analyze of Gilsonite

| 2 | Moisture content | ASTM- D3174 | 1% |
| 3 | Solubility in CS2 | ASTM-D4 | 85~98 |
| 4 | Volatile matler 900C/min | ASTM 3175 | 44 |
| 5 | C | Element Analyzer | 54 |
| 6 | H | Element Analyzer | 6.5 |
| 7 | N | ASTM-D3228 | 0.68 |
| 8 | S | IP242 | 4+2 |
| 9 | O | Element Analyzer | 5.1 |
| 10 | Softening point | ————– | 180-230 |
Gilsonite is a solid hydrocarbon that occurs naturally in many places, including Iran. It is also called asphaltite or natural bitumen. The exact mine and location within the Gilsonite zone from which the mineral is mined determine its composition and quality, which can vary greatly. Gilsonite is typically better acceptable for use in a variety of industrial applications due to its reduced impurity levels when mined from the core of a deposit. However, in order to make Gilsonite powder, it is necessary to remove contaminants, such as soil and other minerals, from Gilsonite that is recovered from the mine’s peripheral.
These contaminants have the potential to greatly alter the final Gilsonite product’s quality and characteristics. Industrial uses of Gilsonite, such as asphalt manufacture and oil well drilling, can be negatively impacted by high quantities of impurities, which alter its physical and chemical properties. Hence, a comprehensive analysis of the Gilsonite is necessary to guarantee that it satisfies the necessary criteria for its designated use. Ash, moisture, solubility, volatile matter, and components including carbon, hydrogen, nitrogen, sulfur, and oxygen are usually tested for in an analysis. Furthermore, Gilsonite’s adaptability for various temperature settings is determined by measuring its softening point.
