• Magnetite: South Australia''s potential

    Magnetite ore and processing. A general processing circuit for magnetite ore is initial crushing and screening of run of mine (ROM) ore to <6 mm. The ore is then milled to a specified grind size to liberate the iron minerals from the gangue, then processed further to produce a magnetite concentrate, commonly by a wet magnetic separation process.
