At the age of 89, Yunnan University issued an obituary! He died after ineffective treatment
According to the official website of Yunnan University, Mr. Chen Jing, an outstanding member of the Communist Party of China, an academician of the Chinese Academy of Engineering, a famous expert in rare and precious metal metallurgy in my country, and a professor of Yunnan University, died in Kunming at 6:20 on June 1, 2024 due to ineffective treatment. 89 years old.
Chen Jing was born in Dali, Yunnan in March 1935. He joined the Communist Party of China in May 1960. He graduated from Yunnan University in organic synthesis in August 1958. He worked at the Kunming Institute of Precious Metals from August 1958 to April 2005 and was elected in 1997. He is an academician of the Chinese Academy of Engineering and a concurrent professor at Yunnan University. He has been working at Yunnan University since May 2005.
As a well-known platinum group metal metallurgist in my country, Chen Jing has been committed to the metallurgy and separation analysis of rare and precious metals. He not only studied the chemical reaction principles of precious metal separation methods from the atomic level, but also summarized and proposed the rules between the thermodynamic stability and kinetic inertness of precious metal complexes, the rules of redox reactions, the rules of solubility of poorly soluble complexes, and nucleophilic substitution reactions. He published a monograph "Metallurgical Chemistry of Platinum Group Metals" in the Science Press, and led the team to take the lead in using solid phase extraction technology to enrich and separate rare precious metals in China, and established a series of new separation and analysis methods for rare and precious metals, forming a Research results that effectively serve local industries.
According to the official website of the Ministry of Education, after the arsenic pollution incident occurred in Yangzonghai in 2008, the Yunnan Provincial Department of Science and Technology launched a global public bidding through the bidding website to find treatment methods. However, due to the large volume of Yangzonghai, and the treatment goal was to remove arsenic The concentration dropped from 0.128mg/L to below 0.050mg/L. Therefore, most of the more than 50 units that participated in the bidding gave up. After Chen Jing, who was 74 years old at the time, learned of the news, he took the initiative to lead the team and fought day and night in Yangzonghai for more than two years. Finally, it took less than 1% of the maximum budget of the public bidding to bring Yangzong to the city. The arsenic concentration in the sea has dropped below 0.050mg/L. In the past two years, Chen Jing often visited the site in person to direct the work and adjust the treatment plan according to the progress.
Under the guidance of Chen Jing’s words and deeds, the team teachers not only worked hard and uncomplainingly during the arsenic pollution control process in Yangzonghai, but also were serious and responsible, proactive, and insisted on being role models in their daily teaching and talent training work, and were deeply loved by their classmates. Good reviews and love.
Chen Jing once said: "As a scientific and technological worker, we must establish an overall awareness of serving the national interests. In addition to conducting theoretical explorations in our own profession, we must promote and apply the results to the main battlefield of social economy to make our Research results are transformed into real productivity and contribute to social progress and economic development. This is the need of the country and the people, and this is also the value of our scientific and technological workers.”
In addition to leading the team to creatively propose the use of sedimentation adsorption method to control arsenic pollution in Yangzonghai, it overcame the problem of arsenic pollution control in Yangzonghai, a plateau lake, and made important contributions to national and local economic and social development, Academician Chen Jing It also provides technical support for the development and utilization of low-grade platinum group metal mineral resources in Jinbaoshan, Yunnan. As early as 1971, Jinbaoshan in Dali, Yunnan was discovered to be the second largest platinum group metal mine in China, with a comprehensive potential value of 28 billion yuan. However, due to the low grade of the ore, mining is extremely difficult. After the reform and opening up, more than ten international investment companies conducted inspections, but none of them could come up with a reasonable development plan. In response to this problem, Academician Chen Jing led the team to conduct long-term scientific research, breaking through the traditional concept that "platinum group metal ores can only be smelted by fire", and successfully researched the direct oxygen pressure acid leaching and pressurized cyanide treatment of flotation concentrates. The new all-wet process makes the mining of this mine profitable.
During his long-term scientific research and teaching work, Chen Jing worked hard to train young students and was willing to serve as a ladder for others. Under his leadership, the team formulated the scientific research and social service goals of "relying on Yunnan's resources and serving the local economy", formed a benign development mechanism for senior, middle-aged and young people to help and mentor, and established a development model to train young teachers through project research. A series of incentive measures have been formulated. Under the guarantee of these effective management methods and measures, the team's teaching and innovation capabilities have been continuously improved, and the overall strength has been continuously strengthened.
