What elements are in limonite? - Cement Answers

What elements are in limonite? Limonite (/ˈlaɪ. məˌnaɪt/) is an iron ore consisting of a mixture of hydrated iron (III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO (OH)nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely.
