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.

Chemical Grade Limestone for Ironmaking

Sinter Production – Chemical grade limestone is crushed and utilized in the sinter process to help flux iron ore and form a porous concentrated iron product used in the blast furnace process. Additional materials such as mill scale can be introduced with the iron ore and agglomerated to a final product.

Calcium carbonate Essential Chemical Industry

Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

Limestone and Lime – IspatGuru

Jul 07, 2017· 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 composition.

Calcination Wikipedia

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 ΔG° 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.
