does iron ore pellets get moisture determination

Quantification of Moisture Contents in Iron and Manganese Ores

The moisture determination in iron ores is regulated by two ISO standards (2596:2006 and 3087:2011). The hygroscopic moisture may be determined by a gravimetric, Karl Fischer or mass-loss methods. In any of them, the sample is to be heated at 105 ± 2°C for periods of time up to twenty four hours in order to remove the moisture.

Iron Ore Pelletizing Process: An Overview IntechOpen

Jul 10, 2017· The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process

Introduction to Iron ore Pellets and Pelletizing processes

Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %). Normally pellets are reduced considerably faster than sinter

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

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
