Limestone for pH Adjustment in Industrial Wastewater

Limestone certainly does not hurt the process and it can be argued that it does help. However, if the limestone contact tank is going to displace an active chemical treatment stage or system then we must strongly discourage the use of this method. We will never use, under any circumstances, limestone

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.
