| 1 | 西秦岭与埃达克岩和喜马拉雅型花岗岩有关的金铜成矿及找矿问题显示文摘秦岭金矿分布广,目前学术界大多认为分属于造山型和卡林型金矿两类。该区印支期花岗岩发育,大多具有埃达克岩和喜马拉雅型花岗岩(低Sr和Yb)的特点,与金铜矿在时空分布上相关。美国内华达州卡林型金矿是世界级的金矿聚集区,与卡林型金矿有关的第三纪岩浆岩(中酸性火山岩和浅成花岗岩)也具有埃达克岩和喜马拉雅型花岗岩的地球化学特征,暗示内华达卡林型金矿也来源于加厚下地壳的底部。本文讨论了埃达克岩和喜马拉雅型花岗岩有利于成矿的机理,并根据西秦岭金矿与花岗岩分布的关系,提出以夏河-宕昌-两当-凤县为界将西秦岭划分为南北两个成矿区和13个成矿聚集区:北区花岗岩发育,有利于寻找斑岩型、夕卡岩型等热液型金铜矿床;南带侵入岩少而小,有利于寻找远离岩体的金矿(包括卡林型等)。鉴于西秦岭印支期埃达克岩和喜马拉雅型花岗岩发育,金铜尤其是金矿分布多,储量大,且大多与埃达克岩或喜马拉雅型花岗岩有关,可能是中国金矿最具潜力的地区,有利于特大型金铜矿的产出,可能发展成为中国最大的金矿聚集区。为此,建议加强本区花岗岩与金铜成矿关系的研究,革新找矿思路和找矿技术方法,以实现找矿的新突破。 | 张旗 殷先明 殷勇 金惟俊 王元龙 赵彦庆 | 2009 | 岩石学报2009，25，12： | 69 |
| 2 | Geochronology of Baogutu porphyry copper deposit in Western Junggar area, Xinjiang of China显示文摘Baogutu copper deposit in Western Junggar area is a mesoscopic porphyry deposit found in recent years. Study on its geochronology will help further understand ore genesis and regional ore-forming pattern. A series of small quartz-diorite and granodiorite stocks outcrop at Baogutu area, numbered I―X according to their size. A detailed exploration on Number V stock confirmed it as a mesoscopic scale copper deposit, and various exploration work has been carried out on other stocks with ore-forming evidence. This paper studies geochronology of Number V stock using zircon SHRIMP U-Pb and single mineral K-Ar method. Twenty-five SHRIMP ages yield two 206Pb/238U weighed mean ages of 335.6 ± 7.8 Ma and 311.4 ± 3.3 Ma respectively. The older date is considered to be inherited zircon from either surrounding rock tuff or deep granitoid batholith, whereas the younger date is the formation age of ore-bearing intrusion. K-Ar ages of ore-forming biotites, 296.0 ± 3.7 Ma and 297.3 ± 3.8 Ma, in combination with Re-Os age of molybdenite, 310 Ma, confirm the ore-forming age of 310-296 Ma. Granophyre and dioritic porphyrite dikes cut Number V stock and their K-Ar ages range from 278 to 240 Ma, which confine the lower boundary of the mineralization. The framework of Baogutu ore-forming geochrono-logy can be established based on these data. | LIU YuLin GUO LiShuang LIU YuDe SONG HuiXia SONG Biao ZHANG Rui XU FaJun ZHANG YunXiao | 2009 | Science China Earth Sciences2009，52，10： | 33 |
| 3 | Application of Lanthanum in High Strength and High Conductivity Copper Alloys显示文摘China is quite poor in argent resource. Roughly 80% of this industrial argent is imported every year. In order to improve the situation, we took advantage of rare earth (RE) mineral resource and successfully developed the non-argent Lanthanum-tellurium-copper alloy as a substitute for industry argent-copper. In our research, we were able to successfully apply rare earth lanthanum to copper alloy. The defects as porosity, inclusion, etc. originating from nonvacuum melting processing were controlled. Fine grain was obtained. Meanwhile, the comprehensive properties of the copper alloy, such as strength, conductivity and thermal conductivity were improved. The research results in increasing conductivity and thermal conductivity by 5% and 15%, respectively, while the tensile strength is increased by 6% higher than Ag-Cu alloy. The anti-electric corrosion property is good, and there is no argent-cadmium steam population originating from the electric arc effect. The addition of lanthanum further reduces the content of oxygen and hydrogen.The optimum quantity of the addition of RE lanthanum in the copper alloy is 0.010%~0.020%. | 周世杰 赵秉钧 赵桢 金鑫 | 2006 | Journal of Rare Earths2006，24，z2： | 22 |
| 4 | Microfluidic Electrospray Niacin Metal-Organic Frameworks Encapsulated Microcapsules for Wound Healing显示文摘Niacin metal-organic frameworks(MOFs)encapsulated microcapsules with alginate shells and copper-/zinc-niacin framework cores were in situ synthesized by using a microfuidic electrospray approach for wound healing.As the alginate shells were bacteriaresponsively degradable,the niacin MOFs encapsulated microcapsules could intelligently,controllably,and programmably release calcium,copper,and zinc ions,depending on the degree of infections.Te released ions could not only kill microbes by destroying their membrane and inducing the outfow of nutrient substance,but also activate copper/zinc superoxide dismutase(Cu/ZnSOD)to eliminate oxygen free radicals and rescue the cells from oxidative stress injury.Furthermore,the simultaneously released niacin could promote hemangiectasis and absorption of functional metal ions.Tus,the niacin MOFs encapsulated microcapsules were imparted with outstanding antibacterial,antioxidant,and angiogenesis properties.Based on an in vivo study,we have also demonstrated that the chronic wound healing process of an infected full-thickness skin defect model could be signifcantly enhanced by using the niacin MOFs encapsulated microcapsules as therapeutic agent.Terefore,the microfuidic electrospray niacin MOFs encapsulated microcapsules are potential for clinical applications. | Guopu Chen Yunru Yu Xiuwen Wu Gefei Wang Guosheng Gu Feng Wang Jianan Ren Huidan Zhang Yuanjin Zhao | 2019 | Research2019，，1： | 21 |
| 5 | Discovery of the copper deposits with features of the Keweenawan type in the border area of Yunnan and Guizhou provinces显示文摘There existed intense Cu anomaly on the northeastern side of the geochemical boundary with NW strike in the border area between the Yunnan and Guizhou provinces. Through field observation, ore bodies of high-grade native coppers have been found. The copper mineralization was constrained by the ancient volcanic vents of Permian basalt eruption and the overlain strata of carbonaceous argillites. Native coppers with flaky, net veined and impregnated occurrences, fine-grained tenorites and massive chalcocites widely occur in volcanic breccias, tuffs, carbonaceous-siliceous argillites and siliceous bitumen rocks with bed thickness of about 15-80 m. Cu contents vary from 0.5% to 20%. The copper mineralization was tightly related to actinolite-tremolitization, zeolitization and bituminization and involved in extensive reduction environments. Continental flood basalts erupted in mantle plume environments usually have high Cu concentrations (~170 ×10-6 in the Emeishan basalts), which provided a copper source of mineralization. Thus, metallogenesis of the native copper deposits in the Yunnan-Guizhou border area is tightly associated with intensive crust-mantle and organic-inorganic interactions. The tremolitization and chalcocitization indicate that the metallogenic temperatures are in a range of 400-100℃. The geologic background and characteristics of ore and alteration for the native copper deposits in this area are somewhat similar to those of the Keweenawan native copper deposit in Michigan, USA. | 朱炳泉 胡耀国 张正伟 常向阳 | 2003 | Science China Earth Sciences2003，46，z1： | 19 |
| 6 | Re-Os age for molybdenite from the Gangdese porphyry copper belt on Tibetan plateau: Implication for geody- namic setting and duration of the Cu mineralization显示文摘The Gangdese porphyry copper belt consists of one large and five middle-small deposits in addition to dozens of ore-bearing porphyry bodies. The belt trends 350 km long along the EW-striking Gangdese batholith, and locally occurs as a string of beads extending about 50 km within the SN-trending rifting zones (grabens) on the Tibetan plateau. Monzonitic granite- porphyry and quartz monzonitic porphyry, as dominant host rocks, are shoshonitic and potassic calc-alkaline. Available dating data indicate that the ages of the shallow-level emplacement for these porphyries vary from 10 Ma to 18 Ma, which are identical to that of associated potassic calc-alkaline volcanic rocks (10—15 Ma) and mafic dykes (13—18 Ma). The timing and duration of Cu mineralization events are constrained by Re-Os ages for molybdenites from three porphyry copper deposits in the Gangdese porphyry copper belt. Five molybdenite samples from the Nanmu deposit yielded an 187Re-187Os isochron with a highly pre-cise age of (14.76?.22) Ma; six molybdenites from the Chongjiang deposit gave an isochron age of (14.04?.16) Ma. Re-Os model ages for two molybdenite samples from Lakang抏 deposit vary from 13.5 Ma to 13.6 Ma, which are basically identical to isochron ages mentioned above. All the thirteen samples from these three deposits yielded a linear array in the isochron diagram with a higher correlation coefficient of 0.99719 and an isochron age of (14.39?.22) Ma (1s error), suggesting an coeval event of the Cu mineralization and a shared source of ore materials for the Gangdese porphyry copper belt. Compared with the longer-lived felsic magmatic-hydrothermal system, the Cu mineralization is a relatively short event with duration of about 0.5 Ma, and usu-ally occurs in the later-stage of the complicate magmatic system. The emplacement age of the Gangdese porphyries indicates that they intruded after the rapid rising of the Gangdese Mountains at 21—23 Ma, and formed in a post-collision crustal ex-tension environment. Constraint of the NS-trending rifting zones (grabens) on localization of these porphyry bodies implies that the minor east-west stretching dates back to approximately 18 Ma. Highly precise Re-Os age of the Cu mineralization event indicates that a significant east-west extension has commenced at about (14?.5) Ma ago, which is identical to that of the normal faulting in central Tibet (13.5 Ma) and southern Tibet (14 Ma). The strong extension not only provided dilatant conduits for the migration and emplacement of the porphyry magmas pooling near the base of lithosphere, but also resulted in the rapid rising of a large volume of volatile, thus in turn constraining the temporal-spatial localization of the Gangdese porphyry Cu belt. | HOU Zengqian1, QU Xiaoming1, WANG Shuxian2, DU Andao2, GAO Yongfeng3 & HUANG Wei4 1.

| 7 | Pressure leaching technique of smelter dust with high-copper and high-arsenic显示文摘The application of pressure leaching technology in the treatment of high-copper and high-arsenic dust was studied.The pressure leaching technique was determined as follows:the liquid to solid ratio(mL/g)of 5:1,the leaching temperature of 453 K,the retention time of 2 h,the initial sulfuric acid concentration of 0.74 mol/L,the oxygen partial pressure of 0.7 MPa,and the agitation speed of 500 r/min.Under these conditions,95%of copper and 99%of zinc and only 6%of iron in the dust were leached,while about 20%of arsenic was also leached.The leaching technique was optimized further to restrain the leaching of arsenic by adding a small quantity of ferrous iron into the leaching system(c(Fe2 +)=0.036 mol/L).Copper and zinc can be effectively separated from arsenic and iron in the leach.The optimal pressure leaching technique of high-copper and high-arsenic smelter dust is proved to be effective. | 徐志峰 李强 聂华平 | 2010 | Transactions of Nonferrous Metals Society of China2010，20，S1： | 15 |
| 8 | Wilson disease with hepatic presentation in an eight-month-old boy显示文摘Wilson disease is an autosomal recessive disorder of copper metabolism that can cause fatal neurological and hepatic disease if not diagnosed and treated. The youngest child with normal liver function reported so far is an 8-mo-old Japanese boy with low ceruloplasmin levels, and the youngest child with elevated aminotransferase ever reported so far is a 9-mo-old Korean boy with confirmed by genetic testing. Here we report an 8-mo-old Chinese boy presented with elevated liver enzymes, and low serum ceruloplasmin level. Genetic analysis of ATP7 B gene detected two heterozygous disease causing mutations(c.2621C>T/p.A874 V and c.3809A>G/p.N1270S), and parental origins were determined. Persistent elevation of serum aminotransferase in this infant was normalized after zinc therapy. To our best knowledge, this is the youngest patient with elevated liver enzymes ever reported worldwide. We hope that this will raise awareness among pediatricians, leading to earlier diagnosis, timely treatment, and better clinical outcome. | Kuerbanjiang Abuduxikuer Li-Ting Li Yi-Ling Qiu Neng-Li Wang Jian-She Wang | 2015 | World Journal of Gastroenterology2015，21，29： | 14 |
| 9 | A property-oriented design strategy for high performance copper alloys via machine learning显示文摘Traditional strategies for designing new materials with targeted property including methods such as trial and error,and experiences of domain experts,are time and cost consuming.In the present study,we propose a machine learning design system involving three features of machine learning modeling,compositional design and property prediction,which can accelerate the discovery of new materials.We demonstrate better efficiency of on a rapid compositional design of high-performance copper alloys with a targeted ultimate tensile strength of 600–950 MPa and an electrical conductivity of 50.0%international annealed copper standard.There exists a good consistency between the predicted and measured values for three alloys from literatures and two newly made alloys with designed compositions.Our results provide a new recipe to realize the property-oriented compositional design for highperformance complex alloys via machine learning. | Changsheng Wang Huadong Fu Lei Jiang Dezhen Xue Jianxin Xie | 2019 | npj Computational Materials2019，，1： | 12 |
| 10 | Facile synthesis of PtCu nanowires with enhanced electrocatalytic activity显示文摘Using Te nanowires as a sacrificial template, We developed a facile wet-chemical method for the synthesis of bimetallic PtCu nanowires. The as-prepared PtCu nanowires possess a porous structure and high aspect ratio. Transmission electron microscopy, X-ray diffraction, energy dispersive spectroscopy, energy dispersive X-ray spectrum elemental mapping, inductively coupled plasma- mass spectroscopy, and X-ray photoelectron spectroscopy (XPS) measurement techniques are used to analyze the structure and composition of the as-prepared nanowires. The XPS results verify that the incorporation of Cu led to the modified electronic state of Pt. Electrocatalytic results prove that the as-prepared nanowires present superior activity for methanol and ethanol electrooxidation in an alkaline solution. | Wei Hong Jin Wang Erkang Wang | 2015 | Nano Research2015，8，7： | 11 |

| 13 | COMPUTER MODEL OF COPPER SMELTING PROCESS AND DISTRIBUTION BEHAVIORS OF ACCESSORY ELEMENTS显示文摘A computer model has been developed to simulate the distribution behaviors of Ni, Co. Sn. Ph,Zn, As, Sb, Bi, An and Ag in copper smelting process. The model assumes that the copper smelting furnaceis in thermodynamic equilibrium. As many as 21 elements (Cu. S, Fe. Ni, Co. Sn, As, Sb. Bi, Ph. Zn.An. Ag. O, N, C, H, Ca, Mg, Al, and St) and 73 compounds are considered. This model accounts forphysical entrainment in the melts. The predictions by the present computer model are compared with theknown commercial data from Guixi Smelter in China, Home Smelter in Canada and Naoshima Smelter inJapan. The agreements between the computer predictions and the commercial data are excellent, so that thepresent computer model can be used to monitor and optimize the actual industrial operations of copper smelting. It is applicable to simulation of almost all copper pyrometallurgical processes. | Tan Pengfu Zhang Chuanfu(Department of Nonferrous Metallurgy.

| 14 | Microstructure evolution of single crystal copper wires in cold drawing显示文摘The deformation microstructure evolution of single crystal copper wires produced by OCC method has been studied with the help of TEM, EBSD and OM. The results show that there are a small number of dendrites and twins in the undeformed single crystal copper wires. However, it is difficult to observe these dendrites in deformed single crystal copper wires. The structure evolution of deformed single crystal copper wires during drawing process can be divided into three stages. When the true strain is lower than 0.94, macroscopic subdivision of grains is not evident, and the microscopic evolution of deformed structure is that the cells are formed and elongated in drawn direction. When the true strain is between 0.94 and 1.96, mac- roscopic subdivision of grains takes place, and the number of microbands located on {111} and cell blocks is much more than that with the true strain lower than 0.94. When the true strain is larger than 1.96, the macroscopic subdivision of grains becomes more evident than that with the true strain between 0.94 and 1.96, and S-bands structure and lamellar boundaries will be formed. From EBSD analysis, it is found that part of <100> texture resulting from solidifying is transformed into <111> and <112> due to shear deformation, but <100> texture component is still kept in majority. When the true strain is 0.94, the misorientation angle of dislocation boundaries resulting from deformation is lower than 14°. However, when the true strain arrives at 1.96, the misorientation angle of some boundaries will be greater than 50°, and the peak of misorientation angle distribution produced by texture evolution is located in the range between 25° and 30°. | CHEN Jian1,2, YAN Wen1,2, WANG XueYan2 & FAN XinHui2 1 Department of Applied Physics, Northwestern Polytechnical University, Xi’an 710072, China 2 School of Material Science and Chemical Engineering, Xi’an Technological University, Xi’an 710032, China | 2007 | Science China(Technological Sciences)2007，50，6： | 10 |
| 15 | Wilson disease:Histopathological correlations with treatment on follow-up liver biopsies显示文摘AIM:To investigate the progression of hepatic histopathology in serial liver biopsies from Wilson disease(WD)patients.METHODS:We report a group of 12 WD patients treated with zinc and/or penicillamine who underwent multiple follow-up liver biopsies.Demographic,clinical and laboratory data were gathered and all patients underwent an initial biopsy and at least one repeat biopsy.RESULTS:Time to repeat biopsy ranged from 2 to 12 years.Six patients(non-progressors)showed stable hepatic histology or improvement.In one case,we observed improvement of fibrosis from stage 2 to 0.Six patients(progressors)had worsening of fibrosis.There was no significant correlation between the histological findings and serum aminotransferases or copper me-tabolism parameters.The hepatic copper concentration reached normal levels in only two patients:one from the non-progressors and one from the progressors group.The estimated rate of progression of hepatic fibrosis in the entire group was 0 units per year in the time frame between the first and the second liver biopsy(4 years),and 0.25 between the second and the third(3 years).In the progressors group,the rate of progression of liver fibrosis was estimated at 0.11 fibrosis units per year between the first and second biopsy and,0.6 fibrosis units between the second and third biopsy.CONCLUSION:The inability of clinical tools to detect fibrosis progression in WD suggests that a liver biopsy with hepatic copper quantification every 3 years should be considered. | Sandy Cope-Yokoyama Milton J Finegold Giacomo Carlo Sturniolo Kyoungmi Kim Claudia Mescoli Massimo Rugge Valentina Medici | 2010 | World Journal of Gastroenterology2010，16，12： | 10 |
| 16 | Wilson's disease: A review of what we have learned显示文摘Wilson's disease(WD), which results from the defective ATP7 B protein product, is characterized by impaired copper metabolism and its clinical consequences vary from an asymptomatic state to fulminant hepatic failure, chronic liver disease with or without cirrhosis, neurological, and psychiatric manifestations. A high grade of suspicion is warranted to not miss cases of WD, especially less florid cases with only mild elevation of transaminases, or isolated neuropsychiatric involvement. Screening in first and second relatives of index cases is mandatory, and treatment must commence upon establishment of diagnosis. Treatment strategies include chelators such as D-penicillamine and trientine, while zinc salts act as inductors of methallothioneins, which favor a negative copper balance and a reduction of free plasmatic copper. As an orphan disease, research is lacking in this field, especially regarding therapeutic strategies which are associated with better patient compliance and which could eventually also reverse established injury. | Kryssia Isabel Rodriguez-Castro Francisco Javier Hevia-Urrutia Giacomo Carlo Sturniolo | 2015 | World Journal of Hepatology2015，7，29： | 10 |
| 17 | Particles carried by ascending gas flow at the Tongchanghe copper mine,Guizhou Province,China显示文摘We collected and analyzed, using transmission electron microscopy, the particles carried by ascending gas flow in soil above the concealed orebody of the Tongchanghe copper mine, Guizhou Province. Particles of native copper, native copper-iron alloy, and native chromium-iron-copper alloy particles in the ascending gas flow were first discovered. Commonly, they were aggre- gations of relatively small particles. Individual particles within aggregations were subcircular, elliptical, regularly polygonal, or elongate and from 5 to 40 nm in size. The aggregations were subcircular or elliptical and 20-150 nm in size. Chloride, oxide, sulfate, and hydroxide particles containing ore-forming metals in the ascending gas flow were also discovered. The elements of the particles were commonly in a high valence state, suggesting that they were formed in a near-surface oxidizing environment. Discovery of the particles extracted from the ascending gas flow above the Tongchanghe copper mineprovided a powerful tool for exploration for deep concealed orebodies. Our study also showed that native copper, native copper-iron alloys, native chromium-iron-copper alloys, as well as chloride, oxide, sulfate, and hydroxide compounds containing ore-forming metals can be transported in particle form by ascending gas flow below the Earth's surface. | Cao JianJin Liu Chang Xiong ZhiHua Qin TingRong | 2010 | Science China Earth Sciences2010，53，11： | 9 |

| 19 | Copper smelter slag treatment by ammonia solution:Leaching process optimization显示文摘The feasibility of copper smelter slag processing by ammonia solution treatment was investigated. The central composite rotatable design(CCRD) and approximation method were used to determine the optimum conditions of zinc and copper recovery to a solution. The experimental design was done at five levels of the four operating parameters which were the initial concentration of NH–3, the initial Cl ions concentration, leaching time and solid/liquid ratio. Two mathematical models describing dependence of metal recovery on the operating parameters were obtained. The models are successful in predicting the responses. It was found that optimal parameters for zinc and copper recovery are as follows(values for copper are given in brackets): initial CNH3 17.1%(19.9%), initial CCl– 160 g/L(160 g/L), leaching process duration 4.56 h(4.13 h), solid/liquid ratio 0.39(0.53). The maximum Zn and Cu recoveries to solution, obtained experimentally under the conditions, are 81.16% and 56.48%, respectively. | R. Nadirov L. Syzdykova A.

| 20 | Excessive Cu and Zn affecting on distribution of the metals and activities of glycolytic and nitrogen incorporating key enzymes in mycelia of ectomycorrhizal fungi Suillus bovinus显示文摘Concentration of copper and zinc in isolated Suillus bovinus mycelia, used nutrient solution and 0.5 mol/L EDTA mycelia washing solution were measured to investigate the distribution of heavy metals in mycelia growth in excess copper or zinc nutrient solution. Treated with zinc, most of added zinc maintained in used solution, and 9.8%/14.6% was in/on mycelia in treatment, and in treatment 2 was 3.9%/8.0% in/on mycelia. In the copper applications, copper stimulated in more than on mycelia, i.e., 25.9%/4.5% in/on mycelia in treatment, and 7%/18.8% in/on mycelia while most of copper retained in used nutrient solution. Certain amount of copper or zinc uptake by mycelia led to pronounced influence on glycolysis and nitrogen incorporating process of Suillus bovinus, while the tested enzymes kept constant in treatment. In crude extracts of copper treatment 2 mycelia, activities of HK, PFK and GS were inhibited and decrease to 63%, 48% and 38% and GlDH increased by 68% of the control, respectively. The behaviors of these tested enzymes toward zinc corresponded in general with that towards copper. The potential protection of Suillus bovinus for its host plant under excess copper or zinc threaten was discussed. | HUANG Yi, TAO Shu(Department of Urban and Environmental Sciences, Peking University, Beijing 100871, China. | 2001 | Journal of Environmental Sciences2001，13，3： | 9 |
