The olivine crystals and borate containing slag were effectively separated from the CaO-SiO 2 -B 2 O 3 -MgO-Al 2 O 3 system at an optimum precipitating temperature of olivine by utilizing supergravity. The borate containing slag melt went through the filter, whereas the olivine crystals with a larger size of 300 μm-2 500 μm were intercepted by the filter. Consequently, after super-gravity separation with G = 900 at 1 463 K for 5 minutes, the mass fraction of B 2 O 3 in separated borate containing slag was 30.17 wt%, while that of the separated olivine was only 0.009 wt%, and the recovery ratio of boron in separated borate containing slag thus was up to 99.97%.

“…Inspired by previous investigations on selective separating value phases from various slag melts by super-gravity, the super-gravity field enhanced the migrations and concentrations of heterogeneous phases. [11][12][13][14][15] Consequently, the iron-slag separation of gaseous reduced Bayan Obo ore at a low temperature range of 1 373-1 473 K by super-gravity was carried out in current study. Furthermore, the effects of gravity coefficient on the macro and micro structures, the chemical compositions and the mineralogical constitutions of the separated iron, rare earth and fluorite phases were also investigated.…”

The iron-slag separation of gaseous reduced Bayan Obo ore was conducted at a low temperature by super-gravity for the aim of separating rare earth and fluorite phases. Driven by the super-gravity, the slag melt went through the filter, whereas the iron grains were effectively intercepted by the filter. Moreover, the fluorite remained in solid particles and migrated to the lower slag, while all REEs precipitated into Ca 3 (Ce,La,Pr,Nd) 2 [(Si,P)O 4 ] 3 F crystals and concentrated in the bottom slag at 1 373 K-1 473 K.

“…10) Hence, gaseous reduction of the Bayan Obo ore was conducted, and the separation of iron and slag in a super gravitational field was investigated under the inspiration of the successful application of super gravity technology on some other melts. [11][12][13][14] The aim of this study was improving our fundamentally understanding on direct separation of the iron and the REEs from gaseous reduced Bayan Obo ore at 1 473 K, which was below the melting points of iron and fluorite while in the precipitating temperature range of REEs, 6,8) and also providing a potentially feasible process of gaseous reduction combined with low-temperature separation of iron and slag in a super gravitational field for utilizing the lowgrade Bayan Obo ore.…”

The investigations of concentrating iron, slag and britholite-(Ce,La,Pr,Nd) from gaseous reduced Bayan Obo ore were conducted at 1 473 K in a super gravitational field. The results showed that iron grains concentrated at the bottom area along super gravitational direction, whereas the gangue formed the slag in the upper area along the opposite direction, as well as the REEs enriched into britholite-(Ce,La,Pr,Nd) with a typical hexagonal structure and concentrated in the bottom slag. Moreover, the effects of gravity coefficient on both iron-slag separation and the concentration of REEs precipitates were investigated further.
