  INTRODUCTION.edu.tr

  lowintensity magnetic separators and the principal ferromagnetic mineral separated is magnetite (Fe 3 0 4), although hematite (Fe 2 0 3) and siderite (FeCO 3) can be roasted to produce magnetite and hence give good separation. The removal of "tramp" iron from ores can also be regarded as a form of low-intensity magnetic separation.
