Iron ore is common in many mineral forms (hematite, magnetite, goethite, limonite or siderite) and has mineral-specific analysis requirements. Borate fusion with XRF analysis is an extremely robust technique for major and minor elemental analysis in complex mineralization and offers highly precise and accurate results for iron ore samples.

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
