Fe 2 O 3 is also known as hematite, a mineral from which pure Fe 2 O 3 can be obtained via processing and Fe 3 O 4 is known as magnetite for the same reason. These minerals are the feedstock for pure metal …

Understanding the effects of goethitic iron ore – …

Compared with hematite and magnetite, goethite has a much more diverse range of textural forms and occurrences, and its influence on iron ore processing is less understood. Currently, most analysis of the effects of goethite on mine performance considers only the chemistry of the ore and not its textural components. Through improved textural classification of goethitic ores …

Understanding the high-grade 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.
