Calcium Carbonate
Calcium Carbonate is a crystalline chemical compound with its white color and chemical formula CaCO3, which forms a large part of rocks such as limestone and marble, and is used in many applications such as construction and pharmaceutical industries.
Specifications and in-kind characteristics
Extraction, Mining and Product Processing for Industry
We are characterized by the quality of the production process of calcium carbonate across all stages.
We start by extracting from the mines, then crack the ore and grind it into granules with specific sizes and specifications.
Our product is rolled out in domestic and global markets or introduced into the industrial sphere.
1
Extracting
› The cover layer that may be rocky, clay or sandy is removed.
› Clay layer, mechanically fragmented.
› Sand layer, scraped directly and then assembled.
› Solid layer, blasting is used to remove them.
› Limestone mining is done using extraction terraces.
2
Cracking
› Rough cracking is done for pieces smaller than 75 mm and 25 mm.
› Drying in the crusher is done using hot air.
› Transporting granules to conveyor elevators for storage in large custom silos.
› The grinding and classification phase is fed by conveyor belts.
3
Processing
› Classification is done to eliminate impurities and accompanying sand.
› The powder is transferred to customized assembly silos for each separate size.
› Move to the lab to start the processing process and produce calcium carbonate.
› Packing is done according to the type of packing required for consumption.

Calcium Carbonate ApplicationsUses
There is an old close relationship between the human race and limestone, as it is an enormous amount of limestone used by ancient Egyptians. (Pharaohs) in the construction of the pyramids as well as in the construction of the shrines of the saints by the Greeks and the Romans, in addition to which many ancient statues, monuments and sculptures were made of marble, which is a mutated image of limestone, and has also been used in buildings from inside and outside since ancient times.
After the massive industrial revolution, limestone became used in large quantities and this increase began as a result of the substantial growth in the cement industry. Limestone is an essential ore in its industry as well as in the iron and steel industries.
As a result of the development of petrochemical industries after World War II, calcium carbonate has become used for many purposes, for example as a filler in the plastics and paint industry and as an auxiliary agent in rubber processing and as an additive in the paper industry as well as for medical purposes and in the chemical fertilizer industry, pesticides and glass... etc.
Calcium carbonate powder is used in many plastic products produced by the oil industry. The addition of calcium carbonate improves some of the physical properties of the plastic product. It makes it resistant to deformation as it increases its stability and resistance, makes it good external appearance as well as texture and keeps it from offsetting.
The use of calcium carbonate in the plastics industry reduces production costs because it is much cheaper than petroleum and other raw materials and from some plastic products containing calcium carbonate are drainage pipes, Electrical wire, some electrical equipment parts, some automotive parts toys, movies, plastic garbage bags, cutlery food and saucepans, chairs, sanitary and decorative materials, glue... and others.
Calcium carbonate powder is included in the process of manufacturing coating as a filling material to improve some natural properties of coating such as thermal resistance, thermal conductivity, density, viscosity adjustment, prevention of gonorrhea and prevention of absorption in wooden surfaces. Due to its low price, it reduces costs and is an essential material in the paint industry as it forms 30 - 40% of the coating ingredients.
It is used as a filling material to raise rigidity by combining it with the particles of colored or adhesive substances consisting of a coherent and stable substance with high smoothness and the granular size of calcium carbonate powder must be no greater than 20 microns.
Calcium carbonate powder and limestone have been used since the foot in construction, and at present their use has increased as effectively different building materials for example in industrial marble industry, wall panels, floor tiles, stone tiles... and others.
Calcium carbonate powder is used in the paper industry and not only in the giving of whiteness but changes it from acid to neutral, thus it becomes good for preservation for very long periods without rotting as in newsprint which is acidic paper, and from paper types containing calcium carbonate drawing paper, wrapping paper, sculpture paper, advertising paper... and others.
Calcium carbonate is used in the iron and steel industry as an auxiliary material for smelting and reducing the melting temperature of iron and helping to reduce it along with its interaction with the impurities associated with crude such as silica and aluminium, a component of which is malignant with the interaction of calcium oxide with those oxides, while carbon dioxide generated by the reductive atmosphere in the oven is transformed into carbon oxide, which contributes iron to extract from oxygen to oxide. (Iron), and therefore the limestones used must contain as little as possible silica oxides, aluminium and sulfur.
The glass industry is an example of how limestones are used in that industry, as most glass industries consist of a mixture of silica, and soda (Sodium carbonate), lime (calcium oxide), and the role of calcium oxide is to maintain the stability of the chemical composition of glass and give those products the power to make them less broken and the limestones used must be pure and contain the lowest possible iron oxides.
Calcium carbonate powder is added for some kinds of healthy foods and reinforcements, some types of food added are sausages, bread, chewing gum, juices, sweets, biscuit chips and also for medical foods as deficiency boosters for calcium in the body. Pharmaceutical industries such as anti-acidic powder in the stomach, toothpastes, calcium pills, and seamless drugs for the bone... and others.
Calcium carbonate powder is frequently used in products produced by rubber, because it makes the processing process easier as well as reduces costs as a filling material, and from some rubber products included in the carbonate of calcium electric wire, belts and belts, shoes, tyres, hoses, rubber gum, rubber paste, sponges.
In the agricultural field calcium carbonate powder used to equate (alkaline) soil for livestock and fish is used in fertilizer for example as feed for poultry and birds to strengthen eggshells as well as in the marine farming process as the process of cultivation and cultivation of prawns and is also used as medicine for animals.
High purity calcium carbonate powder is used in the manufacture of crystal glass and optical lenses as lenses cameras and in the manufacture of some electrical pieces "lenses", and in schools it is used in chalk, colors, wax chalk and plastic spaces.
