MINERALS

BARITE

What is Barite?

Barite is a mineral consisting of barium sulfate. It most often occurs in hydrothermal veins and as veins in limestones. It is a relatively inert mineral with a high density. It is the primary ore of barium. The most common use of barite is as a weighting agent in drilling muds.

Use of Barite:

Most barite produced is used as a weighting agent in drilling muds. Barite is also used as a pigment in paints and as weighted filler for paper and cloth. It is the primary ore of barium. Barite's high density makes it opaque to x-rays. If it is given to a patient as a drink or enema it can be used to image the shape of internal organs by x-ray.

BENTONITE

What is Bentonite?

Bentonite clay is a fine-grained rock composed mainly of Montmorillonite minerals. Bentonite clay is composed of microscopic platelets consisting of layers of aluminum hydroxide held between layers of silicate atoms. These platelets are stacked one on top of the other

Use of Bentonite:

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 oil well drilling mud. Bentonite also acts as a suspending agent in oil well drilling fluids. Sodium-based bentonite of 75 micron size finds suitability in iron ore palletization for bonding by user industries. Bentonite clay is also used in pyrotechnics, to make end plugs and rocket engine nozzles.

HEMATITE

What is Hematite?

Hematite is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. Weighting material is ground Hematite and meets API Specification 13A Section 8 for drilling fluid Hematite. It is used to increase the density of drilling fluids to control formation pressures. Weighting material has a specific gravity of 4.8 and can be used to increase the density in oil and water-based drilling fluids up to 25 lb/gal (3.0 SG). Weighting material has a higher specific gravity than barite, and so requires less total product to achieve the same fluid density, but tends to be more abrasive than weighting material.

Use Of Hematite:

Hematite is the world’s most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world. The mineral is used to produce pigments, preparations for heavy media separation, radiation shielding, ballast, and many other products.

GILSONITE

What is Gilsonite?

Also known as Natural Bitumen (Natural Asphalt) is a Heavy Hydrocarbon formed directly from crude oil reserves, it is produced when the volatile elements of crude oil are evaporated under immense pressure during many years and with specific physical and geographical conditions, therefore Gilsonite is in Solid shape with dark color and high carbon content and based on each mine geology Gilsonite could have different specifications.

Use of Gilsonite:

  • Gilsonite for road construction and asphalt
  • Gilsonite for roof insulation and isolation
  • Gilsonite for oil drilling as drilling mud

LIMESTONE

What is Limestone?

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes.

Use of Limestone:

Limestone has numerous uses: as a building material, an essential component of concrete (Portland cement), as aggregate for the base of roads, as white pigment or filler in products such as toothpaste or paints, as a chemical feedstock for the production of lime, as a soil conditioner, or as a popular decorative addition to rock gardens.

MICA

What is Mica?

The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.

Use Of Mica:

Paints, Welding electrodes, Gypsum Plasterboards, Automotive Acoustics, Oil Well drillings (on-shore and off shore), Rubber Industry, Plastics industry, Automotive Industry Paints, Decorative Coatings, …

CHROMITE

What is Chromite?

Chromite, the principle ore of the element chromium, is a commercially valuable mineral. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections. Chromite is isomorphous with the mineral Magnesiochromite and is easily confused with it, as they occur in the same environments.

Use Of Chromite:

Chromium is a metal used to induce hardness, toughness, and chemical resistance in steel. The alloy produced is known as "stainless steel." When alloyed with iron and nickel, it produces an alloy known as "nichrome" which is resistant to high temperatures and used to make heating units, ovens, and other appliances. Thin coatings of chromium alloys are used as plating on auto parts, appliances, and other products. Chromium is used as a pigment in paint Chromium is an important pigment in many types of paint, ink, dye, and cosmetics. Trace amounts of chromium produce the color in many minerals and gemstones.

GYPSUM

What is Gypsum?

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO4.2H2O) is very similar to Anhydrite (CaSO4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Use Of Gypsum:

Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, a hardening retarder in portland cement. Varieties of gypsum known as "satin spar" and "alabaster" are used for a variety of ornamental purposes; however, their low hardness limits their durability.
