Han Yuexin, male, born in 1961, holds a Doctorate degree, and is a Professor and Doctoral Supervisor. He is currently Director of the National Local Joint Engineering Research Center for Efficient Development and Utilization Technology of Hard to Mine and Process Iron Ore Resources, and previously served as Dean of the School of Resources and Civil Engineering, Northeastern University, among other posts. His main research interests include the efficient development and utilization of complex and refractory mineral resources, safe disposal and high value utilization of solid waste resources, and preparation of high performance mineral materials. He developed the step by step flotation technology for Anshan type carbonate bearing iron ores, and built a demonstration project with an annual processing capacity of 3 million tons, enabling the development and utilization of carbonate bearing iron ores. He proposed the pre concentration suspension magnetic roasting magnetic separation technology, which has been applied in an industrial production line with an annual output of 1.65 million tons at Jiuquan Iron and Steel Group. This technology has increased the recovery rate by 15 percentage points and is expected to revitalize over 10 billion tons of refractory iron ore resources, yielding remarkable economic and social benefits. Technologies for calcium sulfate whiskers and nano calcium carbonate mineral materials developed by him have been put into industrial production.
In recent years, he has presided over 10 national vertical research projects, including key projects under the 13th Five Year National Key R&D Program, Science and Technology Support Program projects of the Ministry of Science and Technology of China, and key programs of the National Natural Science Foundation of China. He has also undertaken more than 40 horizontal research projects. He has published over 300 academic papers, authored 4 monographs, obtained more than 20 authorized national invention patents, compiled one textbook for mineral processing major under the geological and mining disciplines approved by the Ministry of Education, and won 1 Second Prize of the National Science and Technology Progress Award, 4 First Prizes and 2 Second Prizes of Provincial Ministerial level Science and Technology Progress Awards.
