Geochemical Analysis or Iron Ore SGS

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.
