CHARACTERISTICS AND ORIGIN OF IRON …

The studied iron mineralization is located in the northwestern parts of the Sanandaj – Sirjan Zone (SaSZ) of Iran and extends inside Iraq. This zone is bordered by the Urumieh – Dokhtar magmatic arc and the Zagros Thrust Zone, which is the boundary between the Arabian and Iranian plates. The SaSZ is very important for its iron, manganese and gold mineralizations.

Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson (Yamaguchi et al., 2010). The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, Michigan in ...

Characterization of iron ore by visible and infrared ...

Reflectance and Raman spectroscopies are powerful techniques for the mineralogical characterization of iron ores. Reflectance spectroscopy in the visible (380–750 nm) and infrared (750–14,000 nm) parts of the electromagnetic spectrum provides mineralogical and compositional data on iron ore minerals, such as hematite and goethite, and gangue minerals, such as …
