Calcium carbonate

White pearl, or what is known as calcium carbonate (CaCO3) , is one of the most important raw materials produced by Globe Stone Hills Company. It is a material rich in physical and chemical properties that enable it to enter into many vital industries in multiple fields.

What is calcium carbonate?
It is a natural substance of global importance

Calcium carbonate is a chemical compound with the formula CaCO3, consisting of three main elements: carbon, oxygen, and calcium. It is in the form of a white powder. It is one of the most common chemical compounds on Earth, and is found in many rocks and minerals, including limestone, chalk, and hydrates.
It is a very common substance found in rocks all over the world (particularly as limestone), and is also the primary ingredient in the shells of marine organisms, snails, coal balls, pearls, and eggshells.

Humanity began using calcium carbonate found in limestone rocks since the oldest civilizations, and its use dates back to 14,000 years BC, and its use is still widespread in the modern era.

Calcium carbonate is a valuable resource that meets the needs of many different industries, and many fields benefit from its many benefits, using it on a regular basis.

Advantages of calcium carbonate:

Properties of calcium carbonate

Physical properties:

● Fine white powder.
● Insoluble in water.
● Density of 2.71 grams per cubic centimeter.
● Melting point of 825°C.

Chemical properties:

● A basic compound, which means it reacts with acids to form
calcium salts.
● Acidity 9.

Calcium carbonate extraction:

There are two main methods for extracting calcium carbonate from the ground:

1- Mining:

This is the most common method of extracting all other minerals. The raw material is obtained from underground through a carefully removed process, and a lot of equipment and skilled experts are involved in this process.

In the mining process, heavy equipment is used to remove layers of rock that contain calcium carbonate. These rocks are then transported to a processing facility, where they are ground into a fine powder.

2- Quarrying:

This is another method of extracting calcium carbonate. The quarrying method involves deriving the compound by cutting limestone, marble, chalk, etc. It is the common method of removing limestone.

In the quarrying process, manual or mechanical tools are used to cut limestone from rock. This limestone is then transported to a processing facility, where it is ground into a fine powder.

Differences between the two methods

● Cost: The mining process is more expensive than the quarrying process.
● Efficiency: The quarrying process is more efficient than the mining process, as more calcium carbonate can be extracted per unit area.

The most important uses of calcium carbonate:

● Paper and pulp
● Plastic
● Paints and coatings
● Plasters and sealants
● Rubber
● Food and beverages
● Medicines
● Cosmetics
