Iron ore and ochre mines Minerals and mines

Iron ore is most commonly found as haematite (Fe 2 O 3), pyrite (FeS 2) and goethite (FeO.OH), or as a mixture of hydrated iron oxides known as limonite. In the Mendips, haematite and goethite commonly occur together as either massive, granular, often siliceous masses, or as altered, amorphous, loosely compacted, earthy varieties known as ochre. Two type of ochre occur: red ochre, which is
