Mineral processing - Wikipedia
Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the proce

The recovery of rare earth values from the lean-grade ores requires several stages of mineral beneficiation and hydrometallurgical unit operations. The mineral beneficiation techniques such as gravity concentration, magnetic separation, electrostatic separation, and flotation were employed for the recovery of rare earth minerals.

Summary of the magnetic separation results. An interesting aspect of the magnetic separation of ore S (and partially ore I) is the enrichment of Mn in the magnetic concentrate. The amount of Mn was increased about 4 times from 0.4% and 0.2% in ores S and I, respectively, to 1.6% and 0.8% in the magnetic concentrates.
