Loss On Ignition Iron Ore

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.

Sep 01, 2012 Email to a Friend Abstract. Iron ore concentrate contains different mineral phases viz. hematite, magnetite, goethite, kaolinite, and gibbsite. Presence of some of these phases like goethite, kaolinite, and gibbsite contribute to the loss on ignition (LOI) content of the sample. Iron ore fines (pellet feed) are pelletized for utilization in DRI BF processes.

Iron ore fines (pellet feed) are pelletized for utilization in DRI BF processes. In the present pelletization technology i.e., straight grate and grate kiln processes, the LOI in the ore should be within the range of 2.0-2.5 . LOI content in the iron ore concentrate is found.

On the basis of these analyses, samples of BIF and shale can each be categorized into four groups. Unaltered BIF consists of sub-equal portions of SiO₂ and Fe₂O₃ and moderate amounts of MgO, CaO and loss on ignition (LOI). Compared to these rocks, weathered BIF has significantly higher SiO₂, but lower MgO, CaO and LOI.
