Recovery of Rare Earth Oxides from Flotation Concentrates of ...

Sep 21, 2021Abstract. Historically, the ability to effectively separate carbonate gangue from bastnaesite via flotation has frequently proven to be challenging without sacrificing significant rare earth oxide (REO) grade or recovery. However, in light of the fact that the rare earth bearing minerals often exhibit higher specific gravities than the carbonate gangue, the possibility exists that the use of gravity separation could be used to achieve such a selective separation.

The flotation of rare earth minerals is broadly classified into two categories, such as carbonate mineral (bastnaesite) flotation and phosphate mineral (monazite and xenotime) flotation. The majority of monazite and xenotime minerals are found in placer deposits, and around 60% of them are liberated at finer than 10 μm particle size (Chan 1992 ).

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.

Bastnäsite - Wikipedia

Bastnäsite has cerium, lanthanum and yttrium in its generalized formula but officially the mineral is divided into three minerals based on the predominant rare-earth element. There is bastnäsite-(Ce) with a more accurate formula of (Ce, La)CO 3 F. There is also bastnäsite-(La) with a formula of (La, Ce)CO 3 F. And finally there is bastnäsite-(Y) with a formula of (Y, Ce)CO 3 F.
