2002-6-1  Such a large recovery increase should be contributed to that a large amount of limonite fines were held on the separation plate in the form of hydrophobic flocs, and thus were collected as magnetic concentrate. Clearly, the FMS process is also effective for the recovery of the fine TK limonite, a more weakly magnetic mineral.
