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.
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve.
