| 1 | Thermal decomposition and oxidation of bastnaesite concentrate in inert and oxidative atmosphere显示文摘To clearly elucidate the oxidative roasting behaviors of the bastnaesite, the thermal decomposition and oxidation of the bastnaesite concentrate in inert and oxidative atmosphere have been investigated in detail. Experimental data indicated that the initial decomposition temperature of the concentrate under N_2 atmosphere is 150 ℃ higher than that under O_2 atmosphere,most likely because the oxidation of the cerium induces the decomposition of the concentrate. For the roasted samples under N_2 atmosphere at500 ℃ and above,the oxidation efficiency of the cerium is 19.8%-26.8% because of the fact that rareearth fluorocarbonate is first decomposed to form rare-earth oxyfluoride and CO_2, and the cerium oxyfluoride is then partially oxidized by the CO_2 gas. The rest cerium in these samples can be further oxidized in air at room temperature, with the oxidation efficiency of the cerium gradually increasing to above 80% in 7 d. This can be attributed to the obvious changes in the inner morphology of the roasted samples under N_2 atmosphere at high temperatures, which largely induce the diffusion of the air and improves the oxidation activity of CeOF, and further induces the oxidation of CeOF by the air. XRD and XPS techniques were used to further verify the significant differences in the thermal decomposition behaviors of the bastnaesite concentrate under N_2 and O_2 atmosphere. Moreover, no oxidation of Pr^(3+) to Pr^(4+) in the roasted samples under both N_2 and O_2 atmosphere is observed. This gives an overall understanding of the oxidative roasting of the bastnaesite concentrate without additives. | Longsheng Zhao Liangshi Wang Genghong Shuai Zhiqi Long Dali Cui Xiaowei Huang | 2018 | Journal of Rare Earths2018，36，7： | 10 |
| 2 | ABNORMAL FLOWER AND GRAIN 1 encodes OsMADS6 and determines palea identity and affects rice grain yield and quality显示文摘The palea and lemma are floral organ structures unique to grasses;these structures form the hull and directly affect grain size and quality. However, the molecular mechanisms controlling the development of the hull are not well understood. In this study, we characterized the rice(Oryza sativa) abnormal flower and grain1(afg1) mutant, a new allele of OsMADS6. Similar to previously characterized osmads6 alleles, in the afg1 floret, the palea lost its marginal region and acquired the lemma identity. However, in contrast to other osmads6 alleles, the afg1 mutant showed altered grain size and grain quality, with decreased total starch and amylose contents, and increased protein and soluble sugar contents. The analysis of transcriptional activity suggested that AFG1 is a transcriptional activator and may affect grain size by regulating the expression levels of several genes related to cell expansion and proliferation in the afg1 mutant. These results revealed that AFG1 plays an important role in determining palea identity and affecting grain yield and quality in rice. | Xiaoqi Yu Saisai Xia Qiankun Xu Yuanjiang Cui Ming Gong Dali Zeng Qiang Zhang Lan Shen Guiai Jiao Zhenyu Gao Jiang Hu Guangheng Zhang Li Zhu Longbiao Guo Deyong Ren Qian Qian | 2020 | Science China(Life Sciences)2020，63，2： | 10 |

| 4 | Transplantation of human umbilical cord blood mesenchymal stem cells to treat a rat model of traumatic brain injury显示文摘In the present study, human umbilical cord blood mesenchymal stem cells were injected into a rat model of traumatic brain injury via the tail vein. Results showed that 5-bromodeoxyuridine-labeled cells aggregated around the injury site, surviving up to 4 weeks post-transplantation. In addition, transplantation-related death did not occur, and neurological functions significantly improved. Histological detection revealed attenuated pathological injury in rat brain tissues following human umbilical cord blood mesenchymal stem cell transplantation. In addition, the number of apoptotic cells decreased. Immunohistochemistry and in situ hybridization showed increased expression of brain-derived neurotrophic factor, nerve growth factor, basic fibroblast growth factor, and vascular endothelial growth factor, along with increased microvessel density in surrounding areas of brain injury. Results demonstrated migration of transplanted human umbilical cord blood mesenchymal stem cells into the lesioned boundary zone of rats, as well as increased angiogenesis and expression of related neurotrophic factors in the lesioned boundary zone. | Junjian Zhao Naiyao Chen Na Shen Hui Zhao Dali Wang Jun Shi Yang Wang Xiufeng Cui Zhenyu Yan Hui Xue | 2012 | Neural Regeneration Research2012，7，10： | 5 |

| 6 | Extraction kinetics of neodymium from chloride medium using HEH/EHP saponified with magnesium bicarbonate solution显示文摘Magnesium bicarbonate solution is considered as an environmentally friendly extractant saponification agent for the solvent extraction of rare earth elements due to its advantage of minimum water pollution.In order to reveal the extraction regularity, optimize production-process and guide the use of this new extraction system, the extraction of Nd(Ⅲ) in chloride medium with HEH/EHP saponified by magnesium bicarbonate solution was investigated with the self-designed constant interfacial area cell. Besides, the effects of stirring rate, temperature, specific interfacial area and concentration of Mg-HEH/EHP on the extraction rate of Nd(Ⅲ) were systematically investigated. Results show that, the rate of extraction is governed by both diffusion and chemical reaction, and the extraction reaction takes place at the interface. The apparent activation energy of the extraction reaction is 16.88 kJ/mol. The corresponding rate equation is deduced. The mechanisms and rate-determining step are speculated based on interfacial reaction models, which is consistent with the experimental results. | Hao Lv Xiaowei Huang Zongyu Feng Meng Wang Xu Sun Xinlin Peng Dali Cui Yihanna Hu | 2019 | Journal of Rare Earths2019，37，3： | 4 |
| 7 | Recovery of rare earths and aluminum from FCC waste slag by acid leaching and selective precipitation显示文摘This paper investigated the recovery of rare earth elements(REEs) and aluminum(AI) from the waste slag discharged by FCC catalyst factory(FCC waste slag) via acid leaching and selective precipitation.Analysis methods such as ICP-AES, XRF and XRD were applied to obtain experiment data. The maximum leaching efficiency of REEs and Al was achieved at pH value of 1 and with liquid to solid ratio of 4:1,Under such conditions, 91.01%, 92.24% and 94.77% of La, Ce and Al were extracted at 20 ℃ for 2 h from the FCC waste slag, respectively. The SiO_2 content in the leaching residue was 88.3%, which can be used as an available silicon resource. The REEs can be precipitated in the form of REEs and sodium double sulfate(NaRE(SO_4)_2·xH_2 O) by adding Na_2 SO_4 to the leaching solution, while Al remained in the solution. Afterwards, the pH value of the filtrate was adjusted to 4.5, and Al was precipitated as AI(OH)_3. Finally,NaRE(SO_4)_2·xH_2 O and Al(OH)_3 were converted into RECl_3 and Al_2(SO4)_3 solution,respectively, which were recycled to manufacture zeolite. This process recovered REEs and Al from the FCC waste slag and reduced the emissions of waste slag simultaneously, which has an important economic and environment significance. | Jinyu wang Xiaowei Huang Dali Cui Liangshi Wang Zongyu Feng Bin Hu Zhiqi Long Na Zhao | 2017 | Journal of Rare Earths2017，35，11： | 4 |
| 8 | Aqueous stability of rare earth and thorium elements during hydrochloric acid leaching of roasted bastnaesite显示文摘In order to study the aqueous stability of rare earth and thorium elements and the reaction mechanism of hydrochloric acid leaching of roasted bastnaesite,E_h-pH diagrams for La-,Nd-,Ce-,Th-(Cl)-(F)-H_2 O systems at 20 ℃ were depicted using HSC Chemistry 6.0 software. E_h-pH diagrams of La-, Ce-,Nd-and Th-Cl-H_2 O systems show that trivalent rare earth would be leached into solution by adjusting the acidity of the leaching solution, while tetravalent cerium and thorium would be remained in the leaching residue. And in the case that the pH value of the leaching solution is lower than 2, tetravalent cerium would be partially reduced by chlorine ions(Cl^-), which is well agreed with the industrial production. It can be inferred from E_h-pH diagrams for the systems La-, Nd-,Ce-, Th-F-H_2 O that the leached trivalent rare earth ions(RE^(3+)) and tetravalent thorium ions(Th^(4+)) are preferentially combined with fluorine ions(F) to form sediment during non-reductive acid leaching of roasted bastnaesite. However,when controlling the pH value of the leaching solution below 0, fluorine and tetravalent cerium in the roasted bastnaesite would be leached out in the form of soluble [CeF_3]^+ complex. That means the precipitation of REF_3 and ThF_4·2.5 H_2 O can be avoided in the leaching step. According to E_h-pH diagrams for the system Ce-F-Cl-H_2 O, [CeF_3]^+ in the leaching solution would be reduced to CeF3 precipitate in the presence of Cl^-, that is to say, tetravalent cerium and fluorine would be firstly leached out to form[CeF_3]^+,which would then be reduced to CeF3 precipitate by Cl^-in the hydrochloric acid leaching process of roasted bastnaesite. | Genghong Shuai Longsheng Zhao Liangshi Wang Zhiqi Long Dali Cui | 2017 | Journal of Rare Earths2017，35，12： | 4 |

| 11 | Simultaneous recovery of rare earth elements and phosphorus from phosphate rock by phosphoric acid leaching and selective precipitation:Towards green process显示文摘Phosphate rock has been considered as one of the potential promising resources for rare earth elements(REEs). But the cost issues and the technical challenges caused by the low content of REEs in ores did hinder the further development of REEs recovery technologies. In order to explore a green process for the recovery of REEs from phosphate rock, this study investigates the effects of phosphoric acid concentration, liquid-to-solid ratio(L/S ratio), leaching time and temperature on the leaching efficiencies of the major components from phosphate rock. A REEs recovery of 94.3% and a phosphorus recovery of 95.3%are achieved under the optimal conditions of attacking phosphate rock using 30%P_2 O_5 acid with an L/S ratio of 10:1 and a stirring speed of 250 r/min at 25 ℃ for 4 h. Then,the selective precipitation of REEs with 81.3% REEs recovery is realized by heating up the leaching solution from 25 to 90 ℃ and keeping for4 h. Thereafter, more than 95% phosphoric acid is recovered by H_2 SO_4 and high purity gypsum, more than95% CaSO_4(tested by XRF), is also produced at the same time. Ultimately, a green process that leaches phosphate rock with H_3 PO_4, selectively precipitates REEs from leaching solution by heating up, recovers H_3 PO_4 with H2 SO4 is proposed. Compared with REE recovery in traditional processes, this process owns the merits of simple operation, energy saving and minimum wastes. | Shengxi Wu Longsheng Zhao Liangshi Wang Xiaowei Huang Yunhan Zhang Zongyu Feng Dali Cui | 2019 | Journal of Rare Earths2019，37，6： | 2 |

| 16 | Precipitation-dissolution behaviors of rare earth ions in H_3PO_4-Ca(H_2PO_4)_2 solutions显示文摘In order to achieve deeper understanding of rare earth elements(REEs) behaviors during phosphate rock processing with H_3PO_4. The solubility of REEs in Ca(H_2PO_4)_2-H_3PO_4 solutions with various concentrations of Ca(H_2PO_4)_2 at different temperatures were tested. The results demonstrate that REEs solubility decreases sharply with the increasing concentration of Ca(H_2PO_4)_2. Equations between [REE^(3+)] and [H^+],[H^+] and [Ca^(2+)] in Ca(H_2PO_4)_2-H_3PO_4 solutions were built based on the precipitation-dissolution equilibrium of rare earth phosphates and the ionization equilibrium of H_3PO_4. According to the equations, the decreasing mechanism of REEs solubility caused by elevated concentration of Ca(H_2PO_4)_2 was determined. The mechanism can be illustrated as that the elevated concentration of [H_2 PO_4^-] decreases the concentration of hydrogen ion by retarding the ionization process of H_3PO_4 and directly promotes the precipitation of rare earth phosphates. Furthermore, it can be easy deduced that similar effect would be caused by the other cation impurities(Fe^(3+), Al^(3+), etc.) on REEs solubility based on the mechanism. In addition, superimposed reduction effect on REEs solubility caused by the elevated concentration of Ca(H_2PO_4)_2 and the elevated temperature is found. This superimposed effect leads to a super low solubility of REEs in Ca(H_2PO_4)_2-H_3PO_4 solution. On the basis of the experimental study, outlooks and suggestions for further development of REEs recovery method are given. | Shengxi Wu Longsheng Zhao Liangshi Wang Xiaowei Huang Yunhan Zhang Zongyu Feng Dali Cui | 2019 | Journal of Rare Earths2019，37，5： | 0 |
