    Iron ore consists primarily of hematite (Fe 2 O 3) and magnetite (Fe 3 O 4) in proportions which vary appreciably among ore bodies, as well as variously hydrated hematites, siderite (FeCO 3), and pyrite (FeS 2). Among impurities present, again in widely varying proportions, the most important are lime (CaO), silica (SiO 2) and alumina (Al 2 O 3).

    Siderite Wikipedia

    Siderite is a mineral composed of iron carbonate. It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus. Zinc, magnesium and manganese commonly substitute for the iron resulting in the siderite-smithsonite, siderite-magnesite and siderite-rhodochrosite solid solution series. Siderite has Mohs hardness of

    Iron-rich sedimentary rocks are sedimentary rocks which contain 15 wt.% or more iron.However, most sedimentary rocks contain iron in varying degrees. The majority of these rocks were deposited during specific geologic time periods: The Precambrian (3800 to 570 million years ago), the early Paleozoic (570 to 410 million years ago), and the middle to late Mesozoic (205 to 66 million years ago).
