  Iron ores ? Determination of loss on ignition ? Gravimetric …

  1 Scope. This International Standard specifies a gravimetric method for the determination of the loss in mass of fully-oxidized iron ores, when ignited at 1 000 °C. This method is applicable to a concentration range of 1,0 % (m/m) to 10,0 % (m/m) loss on ignition in natural iron ores, iron ore concentrates and agglomerates.
