| 2 | Current situation and development trend of titanium metal industry in China显示文摘Titanium metal and alloy are key materials for technological development,which significantly promote the development of the hightech economy in China.The consumption of high-end titanium materials and the developmental level of the titanium industry are important indexes of a country’s comprehensive power.However,at present,the application amount and level of high-end titanium materials in China are limited by many factors,including the dependence of raw materials on imports,high processing cost,and structural imbalance of products.Based on the characteristics of titanium resources and the current situation of the titanium industry,the whole titanium industrial chain in China should be updated.Improving the quality of raw materials is important to produce low-cost,high-end titanium materials using titanium resources with high calcium and magnesium contents in the Panxi region.In addition,the steel-titanium joint production is a vital step to reduce the processing cost of titanium materials.Moreover,the consumption structure of titanium materials should be completed to expand their application.Gradually implementing these suggestions,the overall level of China’s titanium industry will be greatly improved,thereby rapidly establishing an advanced scientific and technological country. | Guanzhou Qiu Yufeng Guo | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，4： | 5 |
| 3 | An electrodeposition approach to metal/metal oxide heterostructures for active hydrogen evolution catalysts in near-neutral electrolytes显示文摘Neutral water splitting is attractive for its use of non-corrosive and environmentally friendly electrolytes.However,catalyst development for hydrogen and oxygen evolution remains a challenge under neutral conditions.Here we report a simple electrodeposition and reductive annealing procedure to produce a highly active Ni-Co-Cr metal/metal oxide heterostructured catalyst directly on Ni foam.The resulting electrocatalyst for hydrogen evolution reaction (HER) requires only 198 mV of overpotential to reach 100 mNcm2 in 1 M potassium phosphate (pH =7.4) and can operate for at least two days without significant performance decay.Scanning transmission electron microscopy coupled with electron energy loss spectroscopy (STEM-EELS) imaging reveals a Ni-Co alloy core decorated with blended oxides layers of NiO,CoO and Cr2O3.The metal/metal oxide interfaces are suggested to be responsible for the high HER activity. | Michael J.Kenney Jianan Erick Huang Yong Zhu Yongtao Meng Mingquan Xu Guanzhou Zhu Wei-Hsuan Hung Yun Kuang Mengchang Lin Xiaoming Sun Wu Zhou Hongjie Dai | 2019 | Nano Research2019，12，6： | 4 |

| 5 | Flotation bubble seed image filling algorithm based on boundary point features显示文摘Bubble seed image filling is an important prerequisite for the image segmentation of flotation bubble that can be used to improve flotation automatic control. These common image filling algorithms in dealing with complex bubble image exists under-filling and over-filling problems. A new filling algorithm based on boundary point feature and scan lines (PFSL) is proposed in the paper. The filling algorithm describes these boundary points of image objects by means of chain codes. The features of each boundary point, including convex points, concave points, left points and right points, are defined by the point's entrancing chain code and leaving chain code. The algorithm firstly finds out all double-matched boundary points based on the features of boundary points, and fill image objects by these double-matched boundary points on scan lines. Experimental results of bubble seed image filling show that under-filling and over-filling problem can be eliminated by the proposed algorithm. | ZhuHong Zhang Guoying Liu Guanzhou Sun Qi | 2012 | International Journal of Mining Science and Technology2012，22，3： | 3 |

| 10 | Inhibition of hematite on acid mine drainage caused by chalcopyrite biodissolution显示文摘Even though biodissolution of chalcopyrite is considered to be one of the key contributors in the formation of acid mine drainage(AMD),there are few studies to control AMD by inhibiting chalcopyrite biodissolution.Therefore,a novel method of using hematite to inhibit chalcopyrite biodissolution was proposed and verified.The results indicated that chalcopyrite biodissolution could be significantly inhibited by hematite,which consequently decreased the formation of AMD.In the presence of hematite,the final biodissolution rate of chalcopyrite decreased from 57.9%to 44.4%at 20 day.This in turn suggested that the formation of AMD was effectively suppressed under such condition.According to the biodissolution results,mineral composition and morphology analyses,and electrochemical analysis,it was shown that hematite promoted the formation and accumulation of passivation substances(jarosite and Cu2-xS)on chalcopyrite surface,thus inhibiting the biodissolution of chalcopyrite and limiting the formation of AMD. | Baojun Yang Wen Luo Maoxin Hong Jun Wang Xueduan Liu Min Gan Guanzhou Qiu | 2022 | Chinese Journal of Chemical Engineering2022，35，4： | 2 |

| 18 | Chalcocite(bio)hydrometallurgy-current state,mechanism,and future directions:A review显示文摘There has been a strong interest in technologies suited for mining and processing of low-grade ores because of the rapid depletion of mineral resources in the world.In most cases,the extraction of copper from such raw materials is achieved by applying the leaching procedures.However,its low extraction efficiency and the long extraction period limit its large-scale commercial applications in copper recovery,even though bioleaching has been widely employed commercially for heap and dump bioleaching of secondary copper sulfide ores.Overcoming the technical challenges requires a better understanding of leaching kinetics and on-site microbial activities.Herein,this paper reviews the current status of main commercial biomining operations around the world,identifies factors that affect chalcocite dissolution both in chemical leaching and bioleaching,summarizes the related kinetic research,and concludes with a discussion of two on-site chalcocite heap leaching practices.Further,the challenges and innovations for the future development of chalcocite hydrometallurgy are presented in the end. | Shichao Yu Rui Liao Baojun Yang Chaojun Fang Zhentang Wang Yuling Liu Baiqiang Wu Jun Wang Guanzhou Qiu | 2022 | Chinese Journal of Chemical Engineering2022，35，1： | 1 |
