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 Fe 2 O 3].Its use is complementary to the determination of
