Spathic Iron Ores

Spathic Iron Ores consist of the carbonate of iron in a comparatively pure state, with but little admixture of earthy matter. The carbonate of manganese is, however, frequently present, but this is not detrimental as it enhances the value of the ore for many purposes. The ore when pure forms rhombohedral crystals of a white colour, but is usually yellow or brown. The chief localities where it occurs are Durham, Somerset and Cornwall in this country, and in Styria, Carinthia, and Prussia.
