Iron ore lump and sinter fines are examples of DSOs, which are mined predominantly from areas such as Australia's Pilbara and Brazil's Carajas regions, where geological processes have led to iron content levels of between 55% and 65%. These ore types require little processing beyond crushing and screening before being 'directly-shipped ...
Iron ore being unloaded at docks in Toledo, Ohio. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe ...
