 · The different textural types of hematite directly affect the iron ore beneficiation and agglomeration processes, and the quality of produced sinters and pellets (Libaneo et al., 2001, Vieira et al., 2003, Ribeiro and Vieira, 2004). For instance, granular and lamellar hematites increase the strength of pellets, but reduce their porosity and reducibility. On the other hand, microcrystalline ...

Massive hematite ore (MHO) is a special highgrade iron ore used as lump ore in the process of obtaining direct reduced iron (DRI). The influence of porosity on the reducibility was investigated using optical and scanning electron microscopes. Hematite is the main component of the samples and occurs as granular crystals (10 m), microplates (1 m) and euhedral martite (10 to 30 m).

Hematite and Itabirite

Hematite is often cheaper to process than other forms of iron ore as it generally does not require beneficiation due to its higher iron content. However, hematite ores may contain higher concentrations of contaminant elements (such as phosphorus, alumina and silica) and may therefore need to be blended prior to smelting. Export grade hematite ores generally grade above 60% iron content. What ...

These martitehematite ores appear to have formed by a lowtemperature process in which some of the goethite or its precursor, in ores of the martite(hematite)goethite type, has converted to platy hematite in contrast to the finegrained and often cryptocrystalline material of the normal ores. This partial transformation has resulted in increased permeability of the deposits which in turn ...
