  • Geochemical Analysis or Iron Ore

    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.

  • Extraction of Iron Iron Mining Iron Ore Processing

    Hematite is easier to floated than magnetic which could be separated by positive flotation. As the density of iron ore is much higher than that of gangue mineral gangue mineral is more likely to attach to the foam than iron ore. Therefore for the extraction of iron ore reverse flotation is more advantageous than positive flotation.
