How is limestone extracted from the earth?
Limestone is extracted from the rock either by blasting or mechanical excavation depending on the hardness of the rock. rough crushing. After crushing the stone is sorted into different fractions by screening, after which it goes to be processed further. In the grinding process the limestone is ground to a fine powder.
Why is limestone so important?
What important compound does limestone yield? Limestone is a source of lime (calcium oxide), which is used in steel manufacturing, mining, paper production, water treatment and purification, and plastic production. Lime also has major applications in the manufacture of glass and in agriculture.
What is the byproduct of 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).

Can humans make gold?
As such, no series of chemical reactions can ever create gold. Chemical reactions change the number and shape of the electrons in an atom but leave the nucleus of the atom unchanged. The ancient alchemist dream of creating gold by simply reacting chemicals is therefore impossible.

What is the USGS doing to study limestone?
most USGS research on limestone has focused on mapping deposits, as well as understanding their roles as aquifers and petroleum reservoirs. However, different data are needed to character- ize limestone suitable for construction and other industries. Carbonate rocks need to meet chemical purity require- ments that vary by intended use.
