Understanding the high-grade iron ore market

Iron ores can be formed of several different minerals; the most common are hematite and magnetite. DSOs, including the mid-grade products Rio Tinto and BHP produce from Australia's Pilbara region and the high-grade 65% Fe fines Vale produces in Brazil, are predominantly hematite products.

Industry Overview

Iron ore products are classified according to form and typically categorized as fines, concentrate, pellets, or lump ores: Fines are iron ore processed into a small size below 6 millimeters, which is too small for use in a blast furnace without agglomeration, such as sintering. Processing techniques include crushing, screening, and wet processing.
