iron ore mining magnetite process

  • Magnetite Facts Figures | The Magnetite Network

    Most of Australia's traditional iron ore projects mine ore deposits that are enriched naturally and contain high levels of iron. The Pilbara region is rich in such hematite ore, known also as “direct shipping ore” (DSO). DSO passes through a simple crushing, screening and blending process (beneficiation) before it is shipped

  • Iron ore - Wikipedia

    DSO deposits are typically rarer than the magnetite-bearing BIF or other rocks which form its main source or protolith rock, but are considerably cheaper to mine and process as they require less beneficiation due to the higher iron content. However, DSO ores can contain
