gypsum

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO₄·2H₂O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard/sidewalk chalk, and drywall.
Gypsum, in fact crystalline or crystalline gypsum, is almost 100% pure in crude gypsum mines. Gypsum is naturally white and may be colored due to impurities in the clay organic matter and iron oxide.
Applications and uses in agriculture
• Improving soil structure and terminating clay soils
• Supply calcium needed by plants

• Sodium soaking of alkaline soils

• Clarify the water of muddy ponds

• Activate microscopic creatures

• Supply of sulfur required by plants

Magnesite

Magnesite is a mineral with the chemical formula MgCO.
(magnesium carbonate). Iron, manganese, cobalt and nickel may occur as admixtures, but only in small amounts.
Magnesite occurs as veins in and an alteration product of ultramafic rocks, serpentinite and other magnesium rich rock types in both contact and regional metamorphic terrains. These magnesites are often cryptocrystalline and contain silica in the form of opal or chert.

Magnesite is also present within the regolith above ultramafic rocks as a secondary carbonate within soil and subsoil, where it is deposited as a consequence of dissolution of magnesium-bearing minerals by carbon dioxide in groundwaters.

Magnesite can also be used as a binder in flooring material (magnesite screed). Furthermore, it is being used as a catalyst and filler in the production of synthetic rubber and in the preparation of magnesium chemicals and fertilizers.

In fire assay, magnesite cupels can be used for cupellation as the magnesite cupel will resist the high temperatures involved.

Magnesite can be cut, drilled, and polished to form beads that are used in jewelry-making. Magnesite beads can be dyed into a broad spectrum of bold colors, including a light blue color that mimics the appearance of turquoise.

Limestone (calcium carbonate)

  As everybody know, Limestone (calcium carbonate) is a calcareous rock, sedimentary composed of calcite, although often presents traces of magnesite and other carbonates. This product has a light milky color
calcium carbonate powder with the formula CaCO3 is one of the most widely used mineral powders in the industry, in other words, less industrial can be found in which calcium carbonate powder is not used.
calcium carbonate is used as a filler in industry. Fillers are materials that are added to liquids and solids to make one or more changes in the form of increasing mechanical strength and ductility, reducing or increasing specific gravity, increasing thermal resistance, changing concentration, and reducing cost.
Applications of calcium carbonate in various industries include:
Paint, paper, Insulation, Granule, Crystal and glass, Wire and cable and electrode, Chemical and construction, Ceramic and glazing industry.
The use of calcium carbonate in various industries depends on the purity of the calcium carbonate and the particle size of the calcium carbonate.
In the end, we are able to supply any type of calcium carbonate request with any different analysis, granulation and grading and balk.
In addition to limestone’s, we can supply marbles, natural stones, granites, travertines, etc

Causutic Soda Flak

Caustic soda, or sodium hydroxide, is a thin white sheet that absorbs moisture and is soluble in water. This material is obtained from the evaporation of liquid caustic soda, which is itself produced through membrane technology.

Indications:
- Acid neutralization
- Production of soap and detergents
- Paper and pulp industries
- Oil and gas industries
- pharmaceutical Industries
- Aluminum processing

Calcium Chloride

Dried white granules of calcium chloride are produced through various processes of synthesis, filtration, evaporation, concentration and drying of high quality calcium carbonate and high purity hydrochloric acid.

This product has several uses such as:

    Used in oil and gas drilling

    Melting ice and snow on the road

    Soil stabilization and control of dust and fine dust on roads and deserts

    Accelerates the clogging process in concrete

    Industrial processes such as plastics, calcium salt production, facilitation of wastewater treatment and ...
         

  Other uses for this material include balancing car tires, carbohydrate dryers, refrigerants, food production, food hardening agents, and dozens more.
