  Different Types of Iron Ore

   · Origin of Iron OreBodies. The orebodies, consisting of hematite and limonite, with sometimes a little magnetite, have been formed by two distinct processes: (a) the weathering of siderite into limonite and hematite, as at the outcrop of the original Helen Mine, Michipicoten area; (b) the leaching out of the silica, leaving the concentrated ore in place, as in the Mesabi and other Minnesota ...

  How is Iron Refined from Ore? (with pictures)

  Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore requires ...
