标准范围
This Technical Report describes a gravimetric method for the determination of the loss in mass of nonoxidizediron ores, when ignited at 1 000 °C.This method is applicable to a concentration range of a mass fraction of ?3,0 % to 7,0 % loss on ignitionin natural iron ores, iron ore concentrates and agglomerates, and sinters.The method is not applicable to the following:a) processed ores containing metallic iron (direct reduced iron);b) natural or processed ores in which the sulfur content is higher than a mass fraction of 0,2 %;c) internationally traded ores with combined water greater than 2,5 %.NOTE 1 Loss on ignition can be used as an estimate of combined water.NOTE 2 This method is intended for in-house use and is not intended for referee purposes.
