Marble, like all calcareous rocks, is particularly sensitive to degradation by acid chemicals and to weathering. Acid rains are one of the main degradation agents for marble artifacts. Acid rain contains carbonic, nitric and sulfuric acid, that are produced by oxidation and dissolution in water of gaseous oxides (CO 2, NO 2 and SO 2), present in the air as chemical pollutants.

The corrosion rate of in sulfuric acid is negligible in any concentration from 0 to 99% up to a temperature of at least 150°C. In sulfuric acid at temperatures above 150°C the corrosion rate will have to be considered, but the corrosion rate in high temperature sulfuric acid is magnitudes lower than the corrosion rates of Hastelloy, titanium and zirconium.

There are three basic ways to limit acid mine drainage; prevent sulfuric acid from forming, neutralize the acid after it forms, or collect runoff/seepage to contain the acid. To stop the formation of sulfuric acid, the waste rock and tailings from a mine must be prevented from coming in contact with oxygen.
