origin of iron ore deposits

  • Iron ore

    Magmatic magnetite ore deposits. Another, minor, source of iron ores are magmatic accumulations in layered intrusions which contain a typically titanium bearing magnetite often with vanadium. These ores form a niche market, with specialty smelters used to recover the iron, titanium and vanadium.

    The iron ore trade is, of course, the trade of the Great Lakes, but it was not always so. The premier trade for so many years was grain, then lumber took first place, giving way subsequently to coal. In fact, it was not until 1888 that iron ore became the dominant trade of the Great Lakes.

While it is possible by roasting the ore and by other means to remove the sulphur, the presence of any considerable amount is objectionable. Phosphorus in steel makes it brittle.
