| 1 | Study on hydrometallurgical process and kinetics of manganese extraction from low-grade manganese carbonate ores显示文摘In order to utilize low-grade manganese ore resources effectively, a hydrometallurgical process was developed for manganese extraction in dilute sulfuric acid medium, and the kinetics of leaching manganese was also investigated. At room temperature, manganese from low-grade manganese carbonate ores was extracted by sulfuric acid leaching without reductants. During the extracting process, single-factor analysis method was used to evaluate the effects of grinding fineness, sulfuric acid concentration,liquid-to-solid ratio, agitation rate and leaching time on the leaching efficiencies of Mn and Fe. The optimal leaching conditions are determined as coarse particles of below 2 mm size(without ball-milling),sulfuric acid concentration of 0.86 mol/L, liquid-to-solid ratio of 5:1, agitation rate of 150 r/min and leaching for 180 min at room temperature. Under the optimal conditions, the leaching efficiencies of Mn and Fe are 96.21% and 13.35%, respectively. In addition, through the experiments at different temperatures, it is found that the leaching process follows the shrinking core model under the conditions of changing acid concentration and intermittent reaction device. Moreover, the apparent activations of effective diffusion and chemical reaction in the kinetic model are calculated to be 18.83 and27.15 kJ/mol, respectively. | Liu Youcai Lin Qingquan Li Lifeng Fu Jiangang Zhu Zhongsi Wang Chongqing Qian Dong | 2014 | International Journal of Mining Science and Technology2014，24，4： | 6 |
| 2 | Preparation of chemical manganese dioxide from manganese sulfate显示文摘Chemical Manganese Dioxide (CMD) was prepared by an alkali-oxidation method. There are several virtues to this environmental friendly and clean process, including the nontoxic and harmless reagents and products, easy operations, no pollutants, easily obtained raw materials and moderate reaction conditions. The synthesized manganese dioxide was characterized by XRD and SEM. The particles were small, consisting primarily of α-MnO2 and γ-MnO2. Experimental results showed that the optimum conditions were: MnSO4?H2O to NaOH ratio, 1.0:2.4; catalyst concentration (catalyst TF-2), 6% of the MnSO4; initial solution pH, 11; reaction time and temperature, 20 min and 80 °C; air flow, 0.20 m3/h; and, agitation rate, 700 r/min. The conversion of MnSO4 can exceed 80% under these optimum conditions. | FU Jiangang, HE Zhangxing, WANG Hui, LIANG Wei, GUO Chao College of Chemistry and Chemical Engineering, Central South University, Changsha 410083, China | 2010 | Mining Science and Technology2010，20，6： | 5 |
| 3 | Upper Cretaceous trench deposits of the Neo-Tethyan subduction zone: Jiachala Formation from Yarlung Zangbo suture zone in Tibet, China显示文摘The history of convergence between the India and the Asia plates, and of their subsequent collision which triggered the Himalayan orogeny is recorded in the Yarlung Zangbo suture zone. Exposed along the southern side of the suture, turbidites of the the Jiachala Formation fed largely from the Gangdese arc have long been considered as post-collisional foreland-basin deposits based on the reported occurrence of Paleocene-early Eocene dinoflagellate cysts and pollen assemblages. Because magmatic activity in the Gangdese arc continued through the Late Cretaceous and Paleogene, this scenario is incompatible with U-Pb ages of detrital zircons invariably older than the latest Cretaceous. To solve this conundrum, we carried out detailed stratigraphic, sedimentological, paleontological, and provenance analyses in the Gyangze and Sajia areas of southern Tibet,China. The Jiachala Formation consists of submarine fan deposits that lie in fault contact with the Zongzhuo Formation.Sandstone petrography together with U-Pb ages and Hf isotope ratios of detrital zircons indicate provenance from the Gangdese arc and central Lhasa terrane. Well preserved pollen or dinoflagellate cysts microfossils were not found in spite of careful research, and the youngest age obtained from zircon grain was ~84 Ma. Based on sedimentary facies, provenance analysis and tectonic position, we suggest that the Jiachala Formation was deposited during the Late Cretaceous(~88–84 Ma) in the trench formed along the southern edge of Asia during subduction of Neo-Tethyan oceanic lithosphere. | Hanpu FU Xiumian HU Erica M.

| 4 | Redefinition and Formation Age of the Tanjianshan Group in Xitieshan Region, Qinghai显示文摘The Tanjianshan Group, which was previously divided into a, b, c and d formations, has been controversial for a long time. It mainly distributes in the northern margin of Qaidam Basin and is an important early Paleozoic greenschist facies metamorphic volcanic sedimentary rock formation. Detailed field investigation and zircon LA-ICPMS U-Pb dating of the key strata suggest that the original lower part of a Formation(a-1) versus the original middle upper of d Formation(d-3 and d-4), the original upper part of a Formation(a-2) and b Formation versus the original lower part of d Formation(d-1 and d-2) of Tanjianshan Group are contemporaneous heterotopic facies volcanicclasolite deposit, respectively. The former formations formed during the middle-late Ordovician(463–458 Ma), while the latter ones formed in the late Ordovician(about 445 Ma). The original c formation of Tanjianshan Group, which formed after 430 Ma, is similar to the Maoniushan Formation of Kunlun Mountains and north Qaidam Basin. According to the rules of stratigraphic division and naming, new stratum formations of Tanjianshan Group are re-built and divided into Duancenggou(O1-2td), Zhongjiangou(O2-3tz) and Xitieshan(O3tx) formations. The original c Formation is separated from Tanjianshan Group and is renamed as the Wuminggou Formation(S3-D1w), which shows a discordant contact with underlying Tanjianshan Group and overlying Amunike Formation(D3a). The zircon U-Pb age frequency spectrogram of Tanjianshan Group indicates three prominent peaks of 430 Ma, 460 Ma and 908 Ma, which is consistent with the metamorphic and magmatic crystallization ages obtained from para- and orthogneisses in north Qaidam HP-UHP metamorphic belt, implying that strong Caledonian and Jinningian tectonic and magmatic events have ever happened in North Qaidam. | LIANG Xinquan FU Jiangang WANG Ce JIANG Ying ZHOU Yun YANG Yongqiang WANG Zeli PAN Chuanchu | 2014 | Acta Geologica Sinica(English Edition)2014，88，2： | 3 |

| 7 | Electro-oxidation process and mechanism of molybdenite decomposition under ultrasonic effect显示文摘According to the characteristics and shortcomings of the traditional roasting process and the electro-oxidation process in the molybdenum metallurgical industry, the ultrasound electro-oxidation process was proposed to strengthen the oxidative decomposition or leaching of mo- lybdenum. Laboratory work was carried out in an electrochemical cell with 15 mm electrode spacing at 25°C under ultrasonic effect. The op- timum conditions were found through experiments. The electro-oxidation mechanism of molybdenite decomposition under ultrasonic was investigated. A model of electro-oxidation mechanism of molybdenum under ultrasonic was given. | JIA Lijuan ZHONG Hong FU Jiangang | 2008 | Rare Metals2008，27，6： | 2 |
| 8 | Hydrothermal Zircon Geochronology in the Shangxu Gold Deposit and its Implication for the Early Cretaceous Orogenic Gold Mineralization in the Middle Bangonghu–Nujiang Suture Zone显示文摘As a typical orogenic gold deposit in Tibet,Shangxu gold deposit is located at the Bangong Lake–Nujiang River Metallogenic Belt in the south of Qinghai–Tibet Plateau.In this paper,zircon U-Pb dating,trace elements and Hf isotopic analysis were performed on Au-bearing quartz veins in the Shangxu gold deposit.Zircons from Au-bearing quartz veins can be divided into three types:detrital,magmatic,and hydrothermal zircons.There are two age peaks in detrital zircons:ca.1700 Ma and ca.2400 Ma.There are two groups of concordant ages including 157±4 Ma(MSWD=0.69)and 120±1 Ma(MSWD=0.19)in magmatic zircons,in whichεH f(t)value of ca.120 Ma from the magmatic zircons range from+8.24 to+12.9.An age of 119±2 Ma(MSWD=0.42)was yielded from hydrothermal zircons,and theirεH f(t)values vary between+15.7 and+16.4.According to sericite Ar-Ar age,this paper suggests that an age of 119±2 Ma from hydrothermal zircons represent the formation age of the Shangxu gold Deposit,and its mineralization should be related to the collision between Lhasa Block and Qiangtang Block.The metallogenic age is basically the same as the diagenetic age of Mugagangri granite,andεH f(t)value of hydrothermal zircon is significantly higher than that of the contemporaneous magmatic zircon,which indicates that there is a genetic relationship between the gold mineralization and the deep crust-mantle magmatism. | HUANG Hanxiao LUOSANG Jiancuo DAI Zuowen LIU Hong FU Jiangang LI Guangming CAO Huawen ZHOU Qing | 2021 | Acta Geologica Sinica(English Edition)2021，95，4： | 1 |

| 16 | Ablation of apoptosis-stimulating of p53 protein 1 protects mice from acute hepatic injury and dysfunction via NF-κB pathway in CCl4-induced hepatotoxicity显示文摘Acute liver injury(ALI)is characterized by apoptosis,inflammation,and oxidative stress,and pathogenic mechanism of ALI is poorly understood.Apoptosis-stimulating of p53 protein 1(ASPP1)is involved in environmental responses,tumor growth,and NF-κB activity,which is of critical importance to ALI.However,the role of ASPP1 in ALI remains largely unexplored.The current study aimed to determine the role of ASPP1 in ALI induced by CCl4 and the underlying mechanism.ASPP1 expression was detected in wild type(WT)mice with ALI induced by CCl4.The function of ASPP1 in ALI induced by CCl4 was investigated using conventional knockout ASPP1 mice.ASPP1 expression significantly increased in ALI mice at 24 hours after CCl4 injection.Deletion of ASSP1 ameliorated apoptosis,inflammation,and necrosis in ALI relative to WT mice.In addition,deficiency of ASPP1 improved liver flood flow as well as ALT and AST levels.The levels of phosphorylated p65 and phosphorylated IκBαwere lower in ASPP1-/-mice than in WT mice with ALI.These results implicate that deletion of ASPP1 may act via inhibition of the NF-кB pathway and protect mice from ALI,which may be a new potential therapeutic target for the treatment of ALI. | Tolessa Muleta Daba Xiang Huang Timur Yagudin Ying Yang Jiangang Wang Xiaoyu Fu Yue Zhao Haiyu Gao Yang Zhou Zhenwei Pan Xiangyu Zhong | 2021 | Frigid Zone Medicine2021，1，1： | 0 |
| 17 | Tprn is essential for the integrity of stereociliary rootlet in cochlear hair cells in mice显示文摘Tprn encodes the taperin protein,which is concentrated in the tapered region of hair cell stereocilia in the inner ear.In humans,TPRN mutations cause autosomal recessive nonsyndromic deafness(DFNB79)by an unknown mechanism.To determine the role of Tprn in hearing,we generated Tprn-null mice by clustered regularly interspaced short palindromic repeat/Cas9 genome-editing technology from a CBA/CaJ background.We observed significant hearing loss and progressive degeneration of stereocilia in the outer hair cells of Tprn-null mice starting from postnatal day 30.Transmission electron microscopy images of stereociliary bundles in the mutant mice showed some stereociliary rootlets with curved shafts.The central cores of the stereociliary rootlets possessed hollow structures with surrounding loose peripheral dense rings.Radixin,a protein expressed at stereocilia tapering,was abnormally dispersed along the stereocilia shafts in Tprn-null mice.The expression levels of radixin andβ-actin significantly decreased.We propose that Tprn is critical to the retention of the integrity of the stereociliary rootlet.Loss of Tprn in Tprn-null mice caused the disruption of the stereociliary rootlet,which resulted in damage to stereociliary bundles and hearing impairments.The generated Tprn-null mice are ideal models of human hereditary deafness DFNB79. | Yuqin Men Xiujuan Li Hailong Tu Aizhen Zhang Xiaolong Fu Zhishuo Wang Yecheng Jin Congzhe Hou Tingting Zhang Sen Zhang Yichen Zhou Boqin Li Jianfeng Li Xiaoyang Sun Haibo Wang Jiangang Gao | 2019 | Frontiers of Medicine2019，13，6： | 0 |
| 18 | Petrogenesis of an Early Cretaceous Xiabie Co I-type Granite in Southern Qiangtang,Tibet:Evidence from Geochemistry,Geochronology,Rb-Sr,Sm-Nd,Lu-Hf and Pb isotopes显示文摘Cretaceous magmatism is widely distributed on both sides of the Bangong-Nujiang suture zone(BNSZ).These rocks record the subduction to closure history of the Bangong-Nujiang Tethys Ocean(BNO)and the collisional history between the Lhasa(LS)and Qiangtang(QT)terranes.The Xiabie Co granite in Nyima County,which located on the southern margin of the QT terrane,Tibet.In this study,whole-rock geochemistry;Rb-Sr,Sm-Nd,and Pb isotopes;and laser ablation inductively coupled mass spectrometry(LA-ICP-MS)zircon U-Pb ages and Lu-Hf isotopes of the Xiabie Co granite in the Nyima area have been studied to constrain its petrogenesis and tectonic setting.Our study can help explain the tectonic evolution of the BNSZ and crust-mantle interaction.Zircon U-Pb dating indicates that the granite was emplaced at ca.120 Ma.The granite contains a small amount of hornblende and has high silicon(SiO2=73.97-78.03 wt%),potassium(K_(2)O=4.75-6.53 wt%),and total alkali(K_(2)O+Na_(2)O=7.98-8.98 wt%)contents;low calcium content(CaO=2.33-4.11 wt%);and variable A/CNK(1.00-1.18)and A/NK(1.09-1.22)values.The P_(2)O_(5) content of the granite negatively correlated with the SiO_(2)content.Thus,the Xiabie Co granite is a weakly peraluminous I-type granite belonging to the high-K calcalkaline to Shoshone series.It is enriched in light rare earth elements(LREEs)and relatively depleted in heavy rare earth elements(HREEs),with LREE/HREE ratios of 8.03-16.40 and La_(N)/Yb_(N) ratios of 10.2-27.1.Samples show right-leaning chondrite-normalized rare earth element patterns with pronounced negative Eu anomalies(Eu/Eu*=0.67-0.76).The primitive-mantle-normalized trace element spider diagrams of the samples are right-leaning zigzag curves,showing relative enrichment in large-ion lithophile elements(LILEs,e.g.,Rb,Th,U,and K)and depletion in high-field-strength elements(HFSEs,e.g.,Nb,P,Ti,and Yb)and displaying striking Sr and Ba negative anomalies.The graniteεHf(t)values were positive(2.9-9.9),whereas the whole-rockεNd(t)values were negative(−2.841 to−2.33).The calculated(^(87)Sr/^(86)Sr)t,(^(206)Pb/^(204)Pb)t,(^(207)Pb/^(204)Pb)t,and(^(208)Pb/^(204)Pb)t values are 0.7014-0.7057(0.7044 on average),18.422-18.851(18.670 on average),15.625-15.642(15.633 on average),and 38.332-38.681(39.571 on average),respectively.On the basis of the aforementioned data,we propose that the Xiabie Co granite was derived from a primitive magma that originated from partial melting of juvenile lower crust with the addition of mantle materials.In addition,strong fractional crystallization occurred during the rock-forming process.Given the geodynamic setting,our new data,together with previously reported achievements,imply that the Xiabie Co granite was formed during the LS-QT collision. | LIU Hong LI Youguo LI Wenchang LI Guangming HUANG Hanxiao MA Dongfang HUANG Yong ZHOU Qing FU Jiangang | 2022 | Acta Geologica Sinica(English Edition)2022，96，3： | 0 |
