    Infrared thermography: An approach for iron ore gradation ...

    A software program for ore gradation was developed which considered that the peak temperature of each ore particle corresponded to its iron content. A threshold was then selected through chemical verification of the ore particles' composition and accordingly the ores were classified as high, medium .

  • BAUXITE THRESHOLD VALUES

    BAUXITE THRESHOLD VALUES

    The iron oxide in bauxite ore is present as hematite or goethite, silica as clay and free quartz, and titania as ilmenite or rutile. Bauxite is an essential ore of aluminium which is one of the most important nonferrous metals used in the modern industry. It is also an essential ore for refractory, abrasive and chemical industries.

    Liquefaction of GARD

    Iron ore fines are generally somewhat finer, but some cargoes also have a significant proportion of lumps above 7mm. The most frequent workaround to avoid this problem is to screen out all particles above 7mm prior to analysis and to conduct the TML test only on the proportion that is below 7mm in size.

    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 hydroxycompounds) and carbon dioxide from may be used as a quality test, commonly carried out for minerals such as iron example, the loss on ignition of fly ash consists of contaminant unburnt fuel.
