For solid samples, an appropriate amount of rare earth raw ores and the sieved samples were ground to a particle size of <1 mm, dried at 105 °C for 1 h in a dry oven, and then cooled to room temperature (23 °C–26 °C) in a dryer. Next, 20 g of the rare earth ore was added to a conical flask containing 100 mL 2 wt% (NH 4) 2 SO 4 solution.

The rare earth minerals have a small monocrystal grain size and are interlocked with other minerals such as barite, fluorite, celestite and calcite, eventually leading to a serious encapsulation phenomenon [13,14,15]. During flotation, the grinding fineness seriously affected the grade and recovery rate of the rare earth ore concentrates.
