In that time frame, it has been found that minerals with larger quantities of iron include pyrite, magnetite, chalcopyrite, hematite, goethite, limonite, greenalite, and siderite. The minerals with the highest iron content will be magnetite, hematite, goethite, and limonite. These minerals range in about 60% to 70%+ in iron content.

Siderite is a member of calcite group minerals, which have a similar structure and form several solid-solution series. The miscibility of the calcite group members is limited though. Of the several possible members of the solid-solution series associated with siderite (FeCO 3), only the smithsonite (ZnCO 3), magnesite (MgCO 3) and rhodochrosite (MnCO 3) varieties are common.

Magnetite, haematite, limonite, siderite are the ores of Iron. Magnetite is the best quality of iron ore and contains 72% pure iron. Haematite contains 60% to 70% pure iron ore. Limonite contains 40% to 60% pure iron. Siderite contains many impurities and has just 40% to 50% pure iron.

Eight siderite samples from hypogene magnetite-siderite-iron silicate alteration (Population 1, S18-25) and 17 ankerite samples from hypogene hematite-ankerite-magnetite alteration (Population 2, A1-17) were collected by microdrilling in order to determine the carbon and oxygen composition of carbonates (Fig. 6).

Siderite is a mineral composed of iron(II) carbonate (FeCO 3).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.

oxidation of siderite created hematite, which acquired a field- controlled, very stable crystalline remanent magnetization and concluded that siderite heated in air did not show magnetic interactions between the dissociation products hematite and maghemite. Hirt and Gehring [1991] studied the low-temperature

Magnetite. Magnetite is the finest ore among all the ores of Iron. Magnetite ore comprises of seventy per cent of iron. The magnetic properties in this ore are appreciable. Fe 3 O 4 is the chemical formula of magnetite ore. Magnetite (Fe3O4) is reduced to Ferrous Oxide (FeO) and then later Iron is extracted from its oxide. Iron ore belts
