  Gradient Magnetic Separator - an overview | ScienceDirect Topics

  13.4.1 Magnetic Field Gradient. Certain elements of design are incorporated in all magnetic separators, whether they are wet or dry separators with low- or high-intensity magnetic fields. The prime requirement is the provision of a high-intensity field in which there is a steep field strength gradient.
