1.Introduction

Established in March 2019, the institute is the first batch of pilot project innovation platforms at Jiangxi University of Science and Technology.

Relying on a number of national scientific research platforms, such as the National Engineering Technology Research Center for the efficient development and utilization of ionic rare earth resources, the Ministry of education laboratory jointly built by the Ministry of education for the development and application of ionic rare earth resources, the engineering research center of the Ministry of education for the efficient development and application of tungsten resources, the national product quality supervision and inspection center, and the academician workstation, the Institute focuses on the development of rare metals, especially rare earth and tungsten The research and development of high-efficiency metallurgical technology and process, clean metallurgical technology, metallurgical process optimization and energy saving, efficient separation and purification of impurities in metallurgical process, metallurgy of special performance compound powder materials and secondary resource waste recovery and other advanced technologies.

The institute has formed a more complete technology researchsystem with present scientific research laboratory about 2000 square meters,with equipment totally valuing 10 million yuan;with devices such as microwave sintering furnaces, high-temperature melt furnaces, Factsage software and so on. The institute had cooperated with Universities as University of Queensland, Central South University;Kunming University of Technology and with enterprises as well as research institutions like Jiangxi Copper Group Corporation, Zhangyuan Tungsten Limited Publicity, Zhangzhou Haisheng Tungsten Tantalum Group Co., Ltd., Changchun Institute, Zhangzhou Nonferrous Metals Research Institute.

At present, the Institute has 16 full-time and part-time researchers, including 15 doctoral degrees, 2 professors, 7 associate professors, 6 lecturers and 1 experimenter; 1 National million talents, 1 national excellent scientific and technological worker, 1 special allowance from the State Council, 1 national excellent teacher, 1 leading talent of Jiangxi Province's "Ganpo talent 555 project", 1 Jiangxi New Century million talents, and 1 Jiangxi Province's "jiangpo talent 555 project" There is one young and middle-aged discipline leader in Jiangxi Province and one high-level discipline leader in Jiangxi Province. Won one provincial teaching achievement award.

The institute has undertaken 20 national scientific research projects such as the Joint Fund of the National Natural Science Foundation, the National 863 Key Plan, the National Science and Technology Support and the National Natural Science Foundation of China whose various research funds amounted to more than 40 million yuan.

The institute published more than 120 academic papers in the core journals at home and abroad, among which SCI / EI had adopted more than 50 articles and declared more than 50 national patents, among which 33 were approved, and 1 software copyright was obtained.

In recent years, the institute has developed a new metallurgical process for white tungsten with low energy consumption and closed circuit circulation, and prepared single crystal ultra-fine APT powder products for the high-value utilization of tungsten with special properties and so on.All mentioned above have been widely used in Zhangyuan tungsten industry, Chenzhou mining, Haitron tungsten industry and other large enterprises.

and won the second prize of national scientific and technological progress in 2018 and won the same award for 2 items in 2016. Related achievements about Copper anode mud ladder recovery of rare precious metals obtained the first prize of scientific and technological progress respectively in 2011, 2019 Jiangxi Province, and first prize inTechnologyprogress of Nonferrous Metals Industry Association in 2018.
