Chen Qingru. Male, Han nationality. Born in Hangzhou, Zhejiang. Academician of China Academy of Engineering, Director, Professor and Doctoral Supervisor of Mineral Processing Engineering Research Center, Department of Energy Utilization and Chemical Engineering, China University of Mining and Technology. He is one of the founders and pioneers of mineral processing and a famous expert educator of mineral processing.

Chen Qingru graduated from Tangshan Jiaotong University 1952. Long-term commitment to mineral processing theory and technology research. 1952 to 1958 worked in the mineral processing department of Beijing Institute of Mining and Technology in China. From 1958 two years later, he was sent by China to Moscow Mining Institute of Soviet Union for further study. After returning from abroad, he served as the deputy director of the media comprehensive utilization room of Beijing Institute of Mining and Technology. Later, he served as deputy director of the Department of Mining Machinery of Beijing Institute of Mining Technology.

Chen Qingquan has made outstanding contributions in the field of mineral processing. He created it by himself? Dry coal preparation? Law. It has attracted worldwide attention in the field of coal preparation. Traditionally, those large coal bases located in the central and western regions of China use the traditional "wet coal preparation" method to prepare coal in the face of serious water shortage. Wet beauty pageant not only consumes a lot of water resources. But also pollute the environment. Because wet coal preparation will produce a lot of wastewater, wastewater treatment will inevitably affect the local environment and ecology. Cause environmental damage.

In 1984, Academician Chen Qingquan put forward the method of "dry medium selection". The water used before is converted into air fluid by modern science and technology for coal preparation. At that time, when many western countries questioned it, Academician Chen Qingquan identified his research results and spent 10 years of hard work. Even because of kidney disease. Surgical nephrectomy. To treat diseases. In such a difficult environment, Academician Chen Qingquan successfully developed? Dry coal preparation? Law. It provides an efficient and clean method for coal-water separation in water-deficient and cold areas. It has made great contributions to the development of China's coal industry.
