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.
Our Pilbara operations – including a world-class, integrated network of 16 iron ore mines, four independent port terminals, a 1,700 kilometre rail network and related infrastructure – are designed to respond rapidly to changes in demand, supported by our Operations Centre in Perth.

Optimization of Solids Concentration in Iron Ore Ball Milling through Modeling and Simulation Universidade Federal do Rio de JaneiroCOPPE/UFRJ, Cx., CEP 21941 972, Rio de Janeiro 68505, Brazil 3 Department of The implication of such a formulation is that the evolution of particle size distribution only depends on the specic energy
distribution of particles of different sizes. It is common practice to represent this distribution in the form of either a frequency distribution curve, or a cumulative (undersize) distribution curve. Weighted distributions A particle size distribution can be represented in different ways with respect to the weighting of individual particles.

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), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
