2017-12-20  Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron

Mössbauer Spectra of Some Magnetic Iron

Mössbauer spectra of iron hydroxide complexes precipitated by a high surface porous silica have been obtained. In the presence of porous silica, oxidation of metallic iron results in the formation of γ-FeOOH and a noncrystalline magnetic oxide.
