The efficient and clean use of co-associated, low-grade complex mineral resources has always been a major national strategic demand. The current process of smelting and smelting is high in energy consumption, heavy in pollution, low in conversion rate, and difficult to separate, thus seriously restricting the development of related industries. The Chinese Academy of Sciences’ process engineering research focuses on important national strategic resources such as vanadium, titanium, chromium and manganese. It closely focuses on the major breakthroughs in the “high-efficiency, clean and comprehensive utilization of characteristic metal deposits†deployed by the Chinese Academy of Sciences, and focuses on the Chinese Academy of Science and Technology Service Network (STS) plan. With the support of the project, relying on the unique sub-molten salt and fluidization platform technologies of the Chinese Academy of Sciences, a series of breakthroughs have been made in the high-efficiency clean conversion of high-chromium vanadium-titanium magnetite, ultra-lean vanadium-titanium-magnetite ore and pyrolusite resources in China. The company has formed core technologies, processes and equipment, including vanadium slag sub-smelting salt method vanadium-chromium co-extraction, ultra-lean vanadium titanium magnetite smelting and smelting integration, and soft manganese ore fluidization reduction, etc., with complete independent intellectual property rights; Chengde Branch Company, Chaoyang Xinhongda Vanadium Titanium Co., Ltd., Jiutai Group and other industry-leading companies have worked closely together and built a series of 10,000-ton or more demonstration projects.
The 50,000-ton/year vanadium slag sub-molten salt method vanadium-chromium total indicator project can achieve 90% and 80% utilization of vanadium and chromium resources. For the first time, simultaneous extraction and separation of vanadium and chromium can be achieved on an industrial scale; the new process can be sourced. To avoid the high-salt ammonia-nitrogen wastewater and harmful kiln gas emissions, it is a green upgrade of the global vanadium extraction technology, and provides an effective solution to crack the clean utilization of China's 3.6 billion tons of high chromium vanadium-titanium magnetite. The sub-fused salt vanadium-chromium co-extraction technology was listed as "China Steel Technology Innovation Global No.1" technology in 2017. This project was also listed in the list of 2017 green manufacturing system integration projects announced by the Ministry of Industry and Information Technology.
The 100,000-ton/year ultra-depleted vanadium titano-magnetite ore beneficiation demonstration project can obtain vanadium-bearing iron ore concentrate and titanium concentrate product, with significant economic benefits; 1000 tons of vanadium-bearing iron concentrate selective reduction iron-wet separation and extraction The vanadium-titanium technology demonstration project achieved an iron yield of 91%, a vanadium recovery rate of 80%, and a titanium recovery rate of 75%. The new technology has the advantages of short process, high recovery of vanadium-titanium and high value-added products, supporting over 10 billion tons in China. Large-scale utilization of ultra-lean vanadium-titanium magnetite. The project was listed in the key project plan of Hebei Province in 2018 and is currently constructing a 50,000-ton/year pilot base.
The world’s first 200,000-tonne soft-manganese fluidized reduction production demonstration line achieves a stable product recovery rate of over 95%, and a 30% reduction in overall process energy consumption compared to traditional processes (110 kgce/t ore), which has effectively promoted China's The high-efficiency, clean use of low-grade pyrolusite resources was selected as a demonstration project for the 2016 “Highlights of the Transformation of Scientific and Technological Achievements of the Chinese Academy of Sciences†and the “20th Anniversary of the Restoration of Wenshan Prefecture, Yunnan Provinceâ€.
On March 26th, the Science and Technology Promotion and Development Bureau of the Chinese Academy of Sciences held an acceptance meeting for the “Industrialization Demonstration Project for the Efficient Use of Vanadium, Titanium, Chromium and Manganese Resources†of the Science and Technology Service Network Program (STS) project of the Chinese Academy of Sciences in Beijing, from Tsinghua University, Beijing University of Science and Technology, Experts from the field of experts and financial experts from the Beijing Non-ferrous Metal Research Institute, Hegang Group, Jiutai Group, Hengshui Hi-tech Zone, and Space Applications Engineering and Technology Center of the Chinese Academy of Sciences formed an acceptance expert group. Du Hao, the researcher of the Project Leader's Process Engineering Institute, and Wang Lina and Associate Researcher Zou Zheng, both responsible for the project, respectively reported on the overall implementation of the project and the implementation of the three topics and accepted questions from the expert group.
Experts at the meeting believe that the project has fully achieved the established objectives and has produced significant economic, environmental, and social effects. It is intended to promote technological transformation in the efficient and clean use of China's major mineral resources, and to support the greenization of the vanadium and titanium industry and the electrolytic manganese industry. Sustainable development provides strong technological support. In summing up, Fu Guangyi, Director of the High Technology Division of the Science and Technology Promotion and Development Bureau of the Chinese Academy of Sciences pointed out that the green upgrade of China’s comprehensive utilization of strategic metal resources is the core task of the “Made in China 2025†green manufacturing field. He hopes that the project will be an opportunity to focus on the country’s major strategy. Demand, facing key issues in the battlefield of science and technology, being brave to innovate, continuing to work hard, fighting well for battles, and making greater contributions to industrial green upgrading and technological innovation.
