"Processes of limestone cave development" by Alan D. Howard
Three processes successively predominate in enlarging original fractures within limestone into cavern passages: (1) early dissolving by acid produced by oxidizing reactions within the groundwater as it flows through the limestone; (2) dissolving caused by the initial undersaturation with respect to calcite of the groundwater when it enters the limestone; and (3) increased dissolving which occurs at the transition .

Limestone
Limestone is a sedimentary rock in the class known as chemical sedimentary rocks. It is composed chiefly of calcite, CaCO3, and constitutes about 10 percent of all sedimentary rocks. Limestone may form inorganically or by biochemical processes. There are many types of limestone because of the variety of conditions under which it is produced.
An Explanation of How Limestone Caves are Formed at Every ...
May 08, 2018· Limestone is a sedimentary rock mainly composed of calcium carbonate and calcite formed by marine organisms like coral, shellfish and algae. It holds up to 10% of the total volume of the sedimentary rocks. A pure limestone is white in color, however, with impurities like sand, minerals and clay, limestones are found in different colors too.
Crushed Limestone Uses Benefits
Limestone aggregate is commonly selected for this purpose. Flux Stone – When crushed, lime can be used for smelting and other metal refining processes. The heat of smelting causes the aggregate to combine with impurities and may be removed from the process as a slag.

Lime Production: Industry Profile US EPA
Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2).
