Mining Of Siderite Iron Ore

Magnetite

Magnetite is a rock mineral and one of the main iron ores, with the stone formula Fe₃O₄. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-…

Hematite

Hematite, also spelled as haematite, is a common iron oxide with the formula Fe₂O₃ and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at tempe…
