Scope

ISO 11536:2015 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.
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 0,2 % (m/m);
c) Natural or processed ores in which the content of partially-oxidized iron is more than 1,0 % (m/m).
