Gilsonite is a naturally occurring asphaltite, having specific gravity substantially equivalent to that of water.Cross reference ice while it is of very light weight in comparison to most solids, it is not porous. Unlike perlite, which is presently employed as an aggregate for the lightening of oil and gas well cement, it does not absorb water, nor is it even wet by water....
The invention relates to a composition comprising an HPHT fluid loss control aid, stable at elevated temperatures and which also acts as an excellent shale stabilizer, bore hold lubricant, sealant for depleted sand, and wall cake conditioner. The HPHT fluid loss control aid broadly comprises a Gilsonite (asphaltite, asfaltit,Gilsonita,uintaite, natural asphalt, natural bitumen) which also contains a surfactant such as a nonionic surfactant...
Gilsonite foundry sand help:
1. Reduce imperfections due to the rapid reaction between the silica sand mold and the oxidized surface of molten iron.
2. Improve sand peel from casting at shakeout.
3.Produce smoother, cleaner casting surface.
4. Minimize imperfections, casting losses, scrap.

mineral bitumen



Gilsonite mine owner and processor of natural asphalt products,Gilsonite depo are located in Kermanshah. At Kermanshah ATDM operates a network of underground Gilsonite mines, a natural asphalt refining plant, and a pulverizing gilsonite factory to powder from 200 mesh to 600 mesh with multiple capabilities on packaging.Our plants have advanced materials handling of Gilsonite and packing facilities, storage silos and bins for 8,000 tons of product and a covered warehouse with multiple loading docks.

Gilsonite lump natural asphalt powder mineral bitumen

Gilsonite is black hard resin and brittle that occurs as asphalt complexes in boarder of Iran and Iraq.Gilsonite composed mainly of NSO compounds and asphaltite with subordinate saturated and aromatic hydrocarbons. Gilsonite is a common drilling mud additive, but it also is used in asphalt paving, roofing and construction paper, paint, ink, explosive, carbon electrodes, and various fuels. At the surface, natural asphalt dikes range from several millimeters to more than 5m thick; some are exposed for up to 39km but most are less than 5km in length. The dike cut across various lower Eocene to Oligocene extension fractures caused by local overpressure in oil shale.ATDM Is Iranian Gilsonite “Natural asphalt” mine owner and manufacturer of lump and powder in various mesh size in powder and raw type lump with application including FLC which is Fluid Loss Control additives in oil well drilling mud and filtrate control as hole stabilizer for high temperature high pressure oil well HTHP, HTLP and as bitumen modifier to mix with asphalt to improve performance and stability of bitumen. The natural asphalt is leading in roof coating, building product coating and road sealcoat crack sealer suppliers. From natural asphalt we are producing drilling fluid which is shale inhibitor in drilling fluid and reacting with shale to prevent sloughing and swelling.

Natural asphalt pellet

We are able to make pellet from natural asphalt and it is using as bitumen modifier in road construction business.Pellet of natural asphalt is availble in 25Kg bag and using right now in ministry of road construction in larg amount.

Natural asphalt drilling fluid as fluid loss control additives and shale control in oil base

Physical shape of natural asphalt and coal is same but specification and analyze is quite difference. The main differences are in softening point and solubility also ash content. natural asphalt in powder or lump form is hydrocarbon with softening point between 150~250°C and coal is carbon with high softening point starting from 300°C.We are selling our natural asphalt with COA certificate of analysis to guaranty the solubility in CS2 ,trichloroethylene and export low ash content. Our company inverting natural asphalt to emulsion and liquid form which has amazing physical properties in filtration and paving, asphalt, ink paint and coating.

Natural bitumen hole stabilizer, inhibitor, bore hole and filtration,HTHP,HTLP, ink stabilizer, paint.

As the world No.1 supplier of Iran natural bitumen and liquid natural bitumen products, we market many different grades of Gilsonite and natural bitumen resins, each with properties tied to a specific end-use. We are shipping direct from mine site and through vessel, truck and train also small quantity by airplane in over 90 countries around the world. The different packing of natural bitumen would be bulk vessel and jumbo bag also micronized powder starting from 200 mesh to 600 mesh in 25Kg multi paper bag on pallet.From our plants we provide customers with a dependable supply of made-to-spec products in a variety of packaging options, including our refined natural bitumen also mixed natural bitumen with several additives for drilling propose in fluid loss control and cementing and obtained through a proprietary solvent extraction process. Our products are carefully screened for mesh, dried to controlled moisture specifications from around 1.5%, classified by particle size, held in large concrete silos until ready for final packaging, and stored in a covered warehouse prior to shipment. Our labs conduct extensive quality controls throughout the production process and every order is shipped with an individual certificate of analysis that guarantees its adherence to specifications.

Mineral asphalt processing to sulfonated asphalt

Our company is producer of liquid mineral called lignosulphonates mineral asphalt which is emulsion shape and modified asphalt and widely using in drilling fluids. Mineral asphalt using in different name and brand on each in each country such as bituminous coal, asphaltum, Uintaite, Sulfonated asphalt, Sulphonated Gilsonite, Natural asphalt, mineral tar, mineral pitch, mineral bitumen, bitumen powder, drilling, asfaltite, asphaltite. Stabilizing shale stratum and reduce rotative torque and preventing jamming also substitute of oil including crude oil, waste engine and diesel oil.

Sulphonated asphalt disperses the solid the solid expansion of drill chips.Mineral asphalt has different analyze and specification since it is mineral and coming from mine same as other minerals and used in more than 160 products, primarily in dark-colored printing inks and paints, oil well drilling muds and cements, asphalt modifiers, foundry sands additives and a wide variety of chemical products. Natural bitumen is compatible with coating material, petroleum resin and oil, pitch and bitumen mixture, vegetable oil and decrease cost of material and homologue with most of materials used in the paint, varnish, primer, mastic, enamel and enamel industry, and at the same time are also highly resistant to acid and alkali materials.

Uses of Gilsonite natural asphalt in paving and mix with asphalt

Gilsonite is used as performance-enhancing agents for asphalt Gilsonite modified paving mixes achieve higher performance grades (PG) and incorporate into an asphalt blend with no need for high shear mulling as in the case with some other modifiers. The use of SBS (styrene-butadiene- styrene) polymers may be partially or totally replaced by, or complemented by the presence of Gilsonite-modified asphalts can have higher stability, reduced deformation, reduced temperature susceptibility and increased resistance to water stripping as compared to non-modified asphalts. A difficulty in using gilsonite as an asphalt modifier is that it is a solid, which is more difficultly handled and incorporated into viscous bitumen.On the other hand, a wide variety of polymers have been used as additives in bitumen compositions; For example, copolyrners derived from styrene and conjugated dienes, such as butadiene or isoprene, are particularly useful, since these copolyrners have good solubility in bitumen compositions and the resulting modified- bitumen compositions have good Theological properties.

Gilsonite price

Gilsonite price is depend on oil price, availability in stock, rainy season and dry season, application, mesh size, packing and volume quantity is different.

MSDS of Gilsonite

MSDS of Gilsonite allow transporting the goods without any problem to worldwide market by any transport mode.

Gilsonite HS code

With HS code of 27149000 is compatible with all waxes and resin, thermoset, thermoplastic, Elastomer, ink and paint.
