LIMESTONE PRIEF
What is Limestone?
Limestone is a common, chemical sedimentary rock formed primarily from calcium carbonate. It is generally light-colored and can also include fossils of calcium carbonate-containing organisms, like corals. Limestone can be found all over the world and is the major type of rock found in karst features (crystal cave systems found in bedrock.
Limestone It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar.
Pulverized limestone is used as a soil conditioner to neutralize acidic soils (agricultural lime).
Is overwhelmed to be used as aggregate—the strong base for many roads as well as in asphalt concrete.
Geological formations of limestone are most of the great petroleum reservoirs;
As a reagent in flue-gasoline desulfurization, it reacts with sulfur dioxide for air pollution manipulate.
Uses of Limestone
- Agriculture
- Industries
- Construction and Architecture
- Animal feed
- Other Uses
Agriculture
We have already said that limestone deposits contain mostly calcium carbonate compound. As such, this compound can be quarried to be used by the farming sector. Usually, limestone is crushed into smaller particles and various grades are produced. Finally, these products are sold as ‘agricultural lime or “Aglime” which is again used to neutralize soil acidity as well as free up soil minerals like phosphates.
Industries
There are several industries that make use of limestone. As such, powdered limestone is used in the textile, paint, paper, rubber, glass and plastic industries amongst others. They are mostly used as fillers. Apart from this, it is used in the steel industry for the production process where limestone is used to remove impurities. The minerals found in limestones are also used in pharmaceuticals, cosmetic products, baking soda, toothpaste, etc.
Construction and Architecture
Here limestone is quarried to service the needs of the building and construction industries. So the stone is cut into either slabs or blocks with specific dimensions. Some of its applications include sculptors, floor tiles, window sills, stair treads, and others. The famous pyramid of Giza in Egypt is made out of limestone.
Additionally, limestones containing clay content are utilized in the production of cement. Limestone aggregate is also used in road and railroad construction.
Other Uses of Limestone
Crushed limestone is used as a filter stone in on-site sewage disposal systems. Limestone in powdered form is also used as a substance to absorb pollutants or control coal mine dust at many coal-mining facilities. Lime which is byproduct of limestone is used to neutralize acids and treat wastewater, industrial sludge, animal waste, and water supplies.
