loss on ignition iron ore

  • ISO 11536:2015(en), Iron ores ? Determination of loss on

    The measurement of loss on ignition (LOI) is a technique widely used in the iron ore industry. Ignition loss is the sum of contributions from the mass loss of volatile compounds water vapour, carbon dioxide and sulfides (due to the decomposition of goethite and carbonaceous materials), and the mass gain due to oxidation [Fe(II) to Fe2O3].

    OverviewTheoryProcedureSafetyOther Uses

    The loss on ignition is reported as part of an elemental or oxide analysis of a mineral. The volatile materials lost usually consist of "combined water" (hydrates and labile hydroxy-compounds) and carbon dioxide from carbonates. It may be used as a quality test, commonly carried out for minerals such as iron ore. For example, the loss on ignition of fly ash consists of contaminant unburnt fuel. In pyroprocessing industries such as lime, calcined bauxite, refractories or cementmanufacture, the loss o
