loss on ignition iron ore

ISO 11536:2015(en), Iron ores ? Determination of loss

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 ].

Quantitative Measurements of Loss on Ignition in Iron

2010-12-1  Laser-induced breakdown spectroscopy (LIBS) and partial least squares regression (PLSR) have been applied to perform quantitative measurements of a multiple-species parameter known as loss on ignition (LOI), in a combined set of run-of-mine (ROM) iron ore samples originating from five different iron ore deposits.

Assessment of evolution of loss on ignition matter

2009-8-28  The thermal removal of bonded water, hydroxyl bonds and other impurities from the iron ore, termed loss on ignition (LOI), affects the efficiency of the conversion process. Each specific type of iron ore has characteristic thermal properties that affect the conversion process and its associated costs.

ISO - ISO 11536:2015 - Iron ores — Determination of

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.

2017-11-1  Hydrated minerals in these hematite iron ores are kaolinite, gibbsite and goethite, which contribute to the loss on ignition (LOI) during thermal decomposition. Experiments in fixed bed have been carried out at variable bed depth (16, 32, 48 and 64 mm), temperature (400–1200 °C) and residence time (30, 45, 60 and 75 min) for iron ore samples.
