Loss On Ignition Iron Ore Sobyin

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

Assessment Of Evolution Of Loss On Ignition Matter During

Although different iron ore reduction processes exist, prior to each reduction type, commonly, the hydroxyl and clay materials present in the iron ores undergo decomposition as a first stage. The mass loss during decomposition of these materials is termed as Loss on Ignition LOI. The aim of this work is to apply a computer aided thermoanalytical technique to evaluate five different iron ore types during

Loss On Drying Loss On Ignition Carbolite Gero

Loss on ignition describes the process of measuring the weight change of a sample after it has been heated to high temperature causing some of its content to burn or to volatilise. Weight change of the sample is monitored during the heating process and this is required, for example, in the determination of organic matter content in materials such as sediment, sludge, soil and waste.
