Limestone when heated starts decomposing into lime (CaO) and carbon dioxide (CO2) at 810 deg C The process is called calcination of limestone It is a thermal treatment process which is carried out for the thermal decomposition of the raw limestone for the removal of LOI (loss on ignition) or carbon dioxide (CO2) part of its compositionAfter the limestone rocks are processed, they are transported to a lime kiln for calcination This is the process where the limestone is heated to a temperature above 1,472ºF for decarbonation, ie, removal of carbon dioxide in gaseous form, to produce quicklime Almost half of the limestoneWhat is Quicklime and How is it Made?

from limestone Lime is made by the process of cakining limestone, that is, burning Che limestone without fusing (melcing) it Pure lime (quicklime, burnt lime, caustic lime) is composed of calcium oxide When treated with water, lime gives off heat, forming calcium hydroxide and is sold commercially as slaked (or hydrated) limeThe limestone mined is used chiefly for the manufacturing of cement, lime and edible lime etc Scientific studies revealed that loss of forest cover, pollution of water, soil and air, depletion of(PDF) LIMESTONE MINING AND ITS ENVIRONMENTAL
Chapter 5 Characterisation of limestone and lime Corrected
The main component of limestone is calcium carbonate (CaCO3), also known as calcite, which is formed by the compaction of the remains of coral animals and plants on the bottoms of oceans It varies from a soft white substance (chalk) to a very hard substance (marble) Most commercial limestone deposits are a brownish rockLimestone is a common type of carbonate sedimentary rockIt is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3)Limestone forms when these minerals precipitate out of water containing dissolved calcium This can take place through both biological and nonbiological processes, though biological processes have likely been moreLimestone Wikipedia

Lithographic limestone is a dense rock with a very fine and very uniform grain size It occurs in thin beds which separate easily to form a very smooth surface In the late 1700s, a printing process known as lithography (named after the stones used) was developed to reproduce images by drawing them on the stone with an oilbased ink, then using that stone to press multiple copies of the imageKolkata Limestone Mining Process Extraction Limestone mining process for kids limestone mining process for kidsMining wikipediaMining is the extraction of valuable minerals or other geological materials from the earth usually from an ore body lode vein seam reef or placer deposit these deposits form a mineralized package that is of economic interest to the miner ores recoveredkolkata is limestone mining bad to live around
