The Erosion of Carbonate Stone

The larger intercept values for limestone as compared to marble show that the water in contact with limestone more closely approaches the equilibrium concentration of 0 55 mmol/L due to limestone's greater porosity and larger surface area Limestone versus Marble Differences in Chemical Erosion

Limestone (mineral)

The most frequent impurities in limestone are dolomite quartz clay minerals and the oxides and hydroxides of iron and manganese as well as pyrite marcasite phosphates gypsum and organic matter The chemical composition of pure limestone approaches the theoretical composition of calcite (56 percent CaCO and 44 percent CaCO 2)

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
