Mica

The micas are an important group of minerals. They represent the classic phyllosilicate mineral and are usually the first minerals to be thought of from this subclass of the Silicates Class. Micas are significant rock forming minerals being found in all three rock types: igneous, metamorphic and sedimentary. Because thin flakes of mica are generally flexible and brittle, it is surprising how resistant and durable mica crystals can be in withstanding high temperatures and pressures in metamorphic regimes as well as the punishment of erosional environments. The term "mica" is so familiar to the general public that it is often considered a mineral in itself. Of course it is actually a group of minerals and most people who are knowledgeable about minerals know the three most common mica minerals: muscovite, biotite, and lepidolite and perhaps a few of the less common micas glauconite, paragonite, phlogopite and zinnwaldite. The Mica Group is actually a rather large group of minerals with over 30 members.

Block and sheet mica are used primarily for electrical and electronic applications where the combination of high dielectric strength, uniform dielectric constant, low power loss, high electrical resistivity, low temperature coefficient, high temperature resistance, chemical resistance, transparency, and ease of fabrication make it an excellent material of choice. In the 1800s the major use for sheet mica was in the manufacture of stove windows, shades for open flame lamps, and for furnace viewing glass. Beginning in the 1890s, the electrical insulating properties of mica became important and large quantities of sheetmica began to be used to manufacture commutator segments for electric motors and generators, in electric irons, toasters, fuse plugs, radio tubes, airplane spark plugs, condensers, capacitors, telephone equipment, radar components and a variety of other electrical and electronic equipment. Currently, the major uses for sheet mica are (Tanner 1994):

• Microwave Windows: Sheet mica can be fabricated into windows having excellent mechanical strength and low power loss using low temperature pressing methods.
• Condenser Mica: Mica has an average dielectric constant of 7, which makes it one of the most dependable types of insulators for all types of electronic applications. Read more . . .

Gilsonite

Gilsonite has a dull, black, coal-like appearance on weathered surfaces and a shiny, black, obsidian-like appearance on fresh surfaces. Fracture surfaces vary from conchoidal to columnar (pencillated) to flaky or scaly. Gilsonite in some localities also has flaky or scaly texture. A third, unusual variety, called jet Gilsonite, has a brilliantly shiny surface, a bluish-black color, and fuses from 390 to 446°F. Gilsonite is now classified into five ranges, according to fusing temperature, which are used in different applications and sell for different prices. Gilsonite from different veins or different parts of veins is sometimes mixed to achieve a product with a specific fusing temperature range. Physical and chemical characteristics of Gilsonite are important for differentiating it from other asphaltites and in determining possible industrial applications. Gilsonite, named after Samuel H. Gilson, was discovered in the 1860s. Gilson was not one of the original discoverers of gilsonite, but his enthusiastic development and promotional efforts linked the material to him, and people in the region began referring to this material as Gilsonite rather than using its scientific name, “uintahite”. The name Gilsonite further solidified in common usage when an early mining company adopted and trademarked the name. 

Iran has many Gilsonite resources and is one of the best Gilsonite suppliers in Middle East. Marjan Mineral Company has a great ability to make all necessary trading communication with most of Gilsonite supplier.

Gilsonite is an important component of today's printing inks, paints & industrial coatings. Gilsonite is used as a hard resin and carbon black dispersant in a variety of coatings. Solutions of Gilsonite are an excellent starting point for blending Gilsonite with other components of a final product formulation. Some formulators convert dry Gilsonite into liquid solution in their own facilities.

• Gilsonite in Asphalt & Bitumen: Gilsonite Natural Asphalt , Natural Bitumen, Hard Asphalt or Hard Asphaltum is used as a performance-enhancing agent for asphalt mixes. Gilsonite-modified paving mixes achieve higher PG grades and incorporate perfectly into the asphalt blend with no need for high shear milling as is the case with many other modifiers.
• Gilsonite in Oil & Gas: Gilsonite is used in drilling mud fluids and oil well cementing. Gilsonite, in a range of softening points and particle sizes, is a standard ingredient in oil-based drilling muds used in shales and other difficult geological formations. The addition of specially-treated Gilsonite to water-based drilling fluids helps minimize hole washout by stabilizing troublesome shales, and seals off highly permeable sands while reducing torque and drag.

Walnut Shell & Pistachio Shell

Walnut Shell abrasive is a hard and fibrous product made from crushed walnut shells in accordance with International Trade Standard. It is the most common type of soft abrasive for industrial use. Walnut Shell has excellent durability, and is now widely used to blast clean and polish soft metals, glass, fiberglass, wood, plastic and stone.
Walnut Shell is ground to various sizes ranging from coarse to extra fine, allowing for a fine degree of control over the desired finish. Like other soft media,Walnut Shell cleans and removes matter from surfaces without damaging underlying material. Walnut shells should be stored in a dry location, away from sources of heat or ignition.
Iran as a prominent name in driedfruit industry, is famous for its unique Persian Walnut. Iran has lots of walnut orchards, therefore Iran is one of the best Walnut Shell supplier in the world. Marjan Mineral Company has great trading communication with most of Walnut Shell producers in Iran. Marjan Mineral Company can provide all necessary conditions for Walnut Shell exporting.

Usage of Walnut Shell in Oil & Gas Industries

Walnut shells exhibit high chemical resistance and are unaffected by pH and temperature, making them useful in oil-based drilling fluids as well as all aqueous systems. Walnut Shell is used as a material to resolve lost circulation challenges prevalent in typical drilling operations; associated with stimulation fluid/drilling mud losses. Walnut Shell is pumped into well with the mud, this practice is intended to seal perforations to create a more secure and less permeable well environment. It is an easy efficient solution without significantly altering drilling fluid consistency. Additionally, Walnut Shell can be removed and/or recycled effortlessly. Read more . . .

Pistachio Shell Usages

The empty Pistachio Shells are useful for recycling in several ways. Practical uses include as a fire starter, just as kindling would be used with crumpled paper; to line the bottom of pots containing houseplants, for drainage and retention of soil for up to two years; as a mulch for shrubs and plants that require acid soils; as a medium for orchids; and as an addition to a compost pile designed for wood items that take longer to decompose than leafy materials, taking up to a year for Pistachio Shells to decompose unless soil is added to the mix. Shells from salted Pistachios can also be placed around the base of plants to deter slugs and snails. Many craft uses for the Shells include holiday tree ornaments, jewelry, mosaics, and rattles. Research indicates that Pistachio Shells may be helpful in cleaning up pollution created by mercury emissions.

Bentonite

Bentonite clay has been used for thousands of years as both an internal and external purification aid. The Egyptians used it to preserve their famous mummies. The ancient Greeks and Romans used it to restore health. The great German naturopaths of the last century hailed clay as one of nature's great remedies. Numerous so-called primitive tribes have used clay for both internal and external purification. The American Indians were evidently the first to use Bentonite for its adsorptive properties. According to one Indian legend, a deposit of natural clay of miraculous medicinal qualities was used by the medicine men in the Bighorn Mountains of Wyoming and Montana. The Indians called this clay "ee-wah-kee," meaning "the mud that heals" (H.H. Tiffany, written commun., 1966). The early pioneers used Bentonite from outcrops called "soap holes" to wash their clothes and to lubricate their wagon wheels (Thorson, undated).
Iranians have known Bentonite and its characteristics since far pasts and used Bentonite as mud shampoo, clay soap and etc. Nowadays Iran has manyBentonite mines and has a great ability to supply Bentonite into other countries. Iran's Bentonites are famous because of their stunning characteristics. It's Marjan Mineral Company's honor that can provide all necessary communications for Bentonite exporting.

Bentonite Usages:

Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets and in foundry and as oilwell drilling mud. Bentonite also acts as a suspending agent in oil well drilling fluids. Bentonite exhibits good green strength along with high hot and dry strength which helps in preventing moulds from breaking or cracking during the pouring or cooling process in the foundry industry. Owing to high green strength resulting from its property to absorb and then release moisture, bentonite is used in iron ore pelletisation. Sodium-based bentonite of 75 micron size finds suitability in iron ore pelletisation for bonding by user industries. Bentonite clay is also used in pyrotechnics, to make end plugs and rocket engine nozzles.
Applications for Bentonite include:

• Drilling: Owing to its rheological properties and thixotropy of aqueous suspensions, bentonite is used as a mud constituent for oil and water well drilling. Its functions are mainly to stabilise the borehole, seal the borehole walls, and remove drill cuttings.Bentonite muds are thus employed for oil and water well drilling, tunnel, and microtunnel drilling.
• Foundry: Bentonite is used as a bonding material in the preparation of moulding sand for the production of cast iron, steel, and non-ferrous casting. The unique properties of bentonite yield green sand moulds with good flowability, compactability, and thermal stability for the production of high quality castings. Read more . . .

Barite

Marjan Mineral Company is one of the best Barite exporters of Iran. Iran has many active Barite mines and Marjan Mineral Company is so honored to have a great trading communication with most of them. Marjan Mineral Company can supply all grades of Barite and export them in various types of packaging:

• 1 Ton Jumbo bags
• 25kg package for powder What

Barite Usages:

• Most of produced Barite is used as a weighting agent in drilling muds. These dense muds are pumped down the drill rod, exit through the cutting bit and return to the surface between the drill rod and the wall of the well. This flow of fluid does two things: 1- Cooling the drill bit; 2- Suspending the rock cuttings produced by the drill and carrying them up to the surface.
• Barite is also used as a pigment in paints and as weighted filler for paper, cloth and rubber. The paper used to make some playing cards has Barite packed between the paper fibers. This gives the paper suitable density that players need to play easily.
• Barite is the major source of barium, which is used to make a wide variety of barium compounds. Some of these are used for x-ray shielding. Barite has the ability to block x-ray and gamma-ray emissions. Barite is used to make high-density concrete to block x-ray emissions in hospitals, powerhouses, and laboratories.
• Barite compounds are also used in diagnostic medical tests. If a patient drinks a small cup of liquid that contains a barium powder in a milkshake consistency, the liquid will coat the patient's esophagus. An x-ray of the throat taken immediately after the "barium swallow" will image the soft tissue of the esophagus (which is usually transparent to x-rays) because the barium is opaque to x-rays and blocks their passage. A "barium enema" can be used in a similar way to image the shape of the colon. Read more . . .
