rare earth ore beneficiation process

In the early 1990s, the rare earth beneficiation process made significant progress, and high-grade, high-recovery rare earth concentrates were obtained from iron ore. These flow charts have been developed: calcination - magnetic separation - flotation, flotation - low magnetic separation, low magnetic flotation - high magnetic separation and
