Selective flocculation, magnetic separation, and flotation of ores
Low-grade, finely disseminated, ores that are not readily amenable to conventional flotation can be upgraded by a selective flocculation-magnetic separation-flotation process. Non-magnetic particles in such an ore can be selectively flocculated either by iron particles in the ore that contain residual magnetite or by the addition of a finely ground magnetic concentrate to the ore.

Iron Ore Magnetic Separation
This fact is demonstrated by washing concentrates from the dry magnetic separation, when the iron content was easily raised from 52 to 58 per cent. This suggested using a combined process of dry magnetic separation and of washing the magnetic product in some such apparatus as the Dorr classifier. The objections to this arrangement are:
