Limestone uses — Science Learning Hub
Calcium oxide, obtained from limestone, acts as a pH regulator when extracting gold from quartz. The chemical extraction of gold from powdered quartz rock uses a solution of sodium cyanide. In this cyanidation process, the pH of the solution needs to be maintained between 10–11 to prevent the production of deadly hydrogen cyanide gas.

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.
