Iron ore and ochre mines Minerals and mines

Typesof Iron OreMineralisationOrefieldsIron ore is most commonly found as haematite (Fe2O3), pyrite (FeS2) 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 silous masses, or as altered, amorphous, loosely compacted, earthy varieties known as ochre. Two type of ochre occur: red ochre, which is mostly impure earthy haematite; and yellow ochre which is earthy goethite, clay and other iron hydroxides. O
