Limestone is the basic raw material for the cement industry.
It is essential for smelting iron ore in the blast furnace..
Why do farmers use limestone?
Some effects of agricultural lime on soil are: it increases the pH of acidic soil, reducing soil acidity and increasing alkalinity. it provides a source of calcium for plants. it improves water penetration for acidic soils.
What are the two main types of limestone?
Generic limestone categoriesBituminous limestone.Carboniferous Limestone – Limestone deposited during the Dinantian Epoch of the Carboniferous Period.Coquina – A sedimentary rock that is composed mostly of fragments of shells.Coral rag.Chalk – A soft, white, porous sedimentary rock made of calcium carbonate.More items…
Why is limestone so important?

What is good about limestone?
Limestone Corrects Soil pH Along with decomposition of natural corrosion and erosion, the soil needs a little love from a neutralizer like limestone. Limestone raises the pH level to a neutral variety beneficial to flowers, usually between 5.5 and 6.5.
Will limestone kill plants?
Applying too much limestone to lawn or garden soils is unlikely kill plants outright. However, as excess lime alters soil chemistry over time, it can dramatically restrict the availability of mineral nutrients that many plants require to thrive. The end result may be unhealthy and unproductive plants.
How is limestone useful to humans?
Limestone can be added to water to remove impurities and pollutants. Since limestone is primarily made of calcium carbonate, a base substance, it can be used to neutralize acidity in industrial waste and run-off. Limestone can also be used to reduce soil acidity for agriculture.

What is made of limestone?
Limestone – a sedimentary rock that composed mostly of calcium carbonate in the form of calcite or aragonite, used as a building stone and in the manufacture of lime, carbon dioxide and cement.
What are the characteristics of limestone?
Limestone is usually gray, but it may also be white, yellow or brown. It is a soft rock and is easily scratched. It will effervesce readily in any common acid.
Where is Limestone most commonly found?
Today Earth has many limestone-forming environments. Most of them are found in shallow water areas between 30 degrees north latitude and 30 degrees south latitude. Limestone is forming in the Caribbean Sea, Indian Ocean, Persian Gulf, Gulf of Mexico, around Pacific Ocean islands, and within the Indonesian archipelago.
