ISO 11536:2015(en), Iron ores ? Determination of …
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 ...
Loss on ignition - Wikipedia
The loss on ignition is reported as part of an elemental or oxide analysis of a mineral. The volatile materials lost usually consist of "combined water" (hydrates and labile hydroxy-compounds) and carbon dioxide from carbonates. It may be used as a quality test, commonly carried out for minerals such as iron ore. For example, the loss on ignition of fly ash consists of contaminant unburnt fuel. In pyroprocessing industries such as lime, calcined bauxite, refractories or cementmanufacture, the loss o…

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.

1-12-2010 · 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.
Study on kinetics of thermal decomposition of low …
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.
The critical importance of optimising performance …
The usage of Australian iron ore has been increasing steadily over this period, changing from hard hematitic to more goethitic ore types, such as pisolitic and Marra Mamba ores, with corresponding changes in the stone and physical composition of the ores, particularly alumina content, loss on ignition (LOI) and particle size.
