Magnetic Separation
Magnetic separators can be of the belt type or drum type. In the drum a permanent magnet is often located inside a rotating shell. Material passes under the drum on a belt. A belt separator is similar except that the magnet is located between pulleys around which a continuous belt travels. Magnetic separation has some limitations.

Flotation-magnetic separation for the beneficiation of rare earth ores
Between 2000 and 2010, magnetic separation and flotation were introduced to beneficiate the Sichuan rare earth ore. A combined "gravity-magnetic-flotation" process was developed (Li et al., 2002, Xiong and Chen, 2009), leading to significant increases in rare earth oxide (REO) content and recovery from the Maoniuping rare earth concentrate.
