Abstract Preview 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.

Jun 08, 2019 高达10%返现 Loss on ignition (LOI) in the mineral represents the chemically bonded water which can be removed at high temperatures only. High LOI in iron ore fines has an adverse affect during pellet induration process. High-LOI iron ore fines are required for detailed laboratory pelletization studies and are used in pellet making.

determination of Loss on Ignition (LOI) from raw iron ore samples by passing them through a number of furnaces with progressively higher temperatures. The LOI is a measure of the water content of the ore and an important step in iron ore analysis. When ore is fed into a blast furnace, the water contained in it will evaporate.

Sequential loss on ignition followed the method proposed by Heiri et al. (2001), with the modifi-cation by Bengtsson and Enell (1986) which takes into account the loss of mass at 105 C and the residues after ignition for the calculation of the LOI. The process was: (1) Dry the sample 12–24 h at 105 C. Calculate the loss on ignition at 105 C (LOI

The L.O.I. is made of contributions from: Volatile compounds : H 2 O+, CO 2, F, Cl, S; in parts also K, Na (if heated for too long);. Added compounds : O 2 (oxidation, e.g. FeO to Fe 2 O 3), later CO 2 (CaO to CaCO 3).. NOTE: For later interpretation of the results of measurement: Due to the escape of volatiles, there will be an increase of mass among all other oxides.
