Siderite an overview | ScienceDirect Topics

There are many minerals containing Fe, but the principal minerals including this element can be noted as hematite Fe 2 O 3, magnetite Fe 3 O 4, limonite Fe(OH) 3, siderite FeCO 3, and pyrite FeS 2 (Bolewski and Manecki, 1993) The background process leading to the presence of Fe in natural water is leaching from rock formation

why is pyrite different from that of hematite and magnetite

Regardless of its setting, hematite is usually found with other ironbearing minerals, especially magnetite, goethite and siderite In Early Proterozoic (25 to 16 billion year ago) iron ore deposits, layers of hematite and other iron oxides alternate with bands of chert (microcrystalline quartz) to form distinctively layered deposits known as

what is iron ore magnetite hematite limonite

iron magnetite hematite siderite pyrite Some examples of minerals in ironrich rocks containing oxides are limonite, hematite, and magnetite An example of a mineral in ironrich rock containing carbonates is siderite and an example of minerals in an ironrich rock containing silicate is chamosite They are often interbedded with limestones
