Processing technology of weak magnetic iron ore

2020-9-11  Flotation is also one of the commonly used methods to separate fine to particulate weakly magnetic iron ore. There are two principle processes, positive flotation and reverse flotation. The former is suitable for quartz hematite ore without easy-floating gangue, and the latter is suitable for ore with easy-floating gangue, and both have production practices.

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. However, REO recovery from Dalucao rare earth ores
