flotation separator for rare earths beneficiation

Flotation-magnetic separation for the beneficiation of ...

2018-4-1  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.
