Is the presence of pyrite in an aggregate likely to be injurious to concrete? The presence of an appreciable amount of pyrite (iron disulphide) is undesirable, since this compound readily decomposes into weak products such as iron sulphate and limonite, along with the formation of sulfuric acid.
Pyrite used to be an important ore for the production of sulfur and sulfuric acid. Today most sulfur is obtained as a byproduct of oil and gas processing. Some sulfur continues to be produced from pyrite as a byproduct of gold production.
