What is the limestone's mining process? Quora

Jan 30, 2017Limestone deposits are found throughout the world. They are mined in a process known as quarrying. This process varies depending on the use of the product. If it is to be made into cement, it is needed in small pieces so that it can be ground and calcined.

Limestone extraction SOLANCIS

Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. If the site presents the desired conditions for quarrying, the next step is the licensing, a procedure which entails various environmental requisites.

Calcination

In limestone calcination, a decomposition process, the chemical reaction is CaCO 3 CaO + CO 2 (g). The standard Gibbs free energy of reaction is approximated as G r = 177,100 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K, or 848 C. Oxidation. In some cases, calcination of a metal results in oxidation of the metal.

Calcitic dolomite and dolomite form mostly in the shallow to deep burial environment, where magnesium in circulating subsurface waters partially replaces calcium and converts calcium rich limestone into magnesium rich limestone through a process called dolomitization, which is nearly complete for dolomite and partially complete for calcitic dolomite. The dolomitization process typically obliterates fossil

DESCRIPTIONRELATION TO MININGUSESLimestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earths sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the U.S. is either limestone or dolomite. As a source for lime, it is used to make paper, plastics, glass, paint, steel, cement, carpets, used in water treatment and purRead More

How Does Limestone Affect the Environment? Reference

Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as karst. Although this doesn't hurt the environment in its natural form, once the limestone is mined out, sinkholes can form and disrupt underground waterways.

Mining

The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.
