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.

Precambrian iron ores of the Singhbhum-North Orissa region occur in eastern India as part of the Iron Ore Group (IOG) within the broad horse-shoe shaped synclinorium. More than 50% of Indian iron ore reserves occur in this region. Massive-hard, flaky-friable, blue dust and lateritic varieties of iron ores are the major ore types, associated with banded hematite, jasper and shales. These ores
Get PriceIron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite, hematite, goethite, limonite or siderite. Ores containing very high quantities of hematite or magnetite are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron
