Understanding the high-grade iron ore market
iron ore market Mineralogy: hematite vs magnetite 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.
