The academician of China Academy of Engineering, who is known as the "king of mineral processing" in China metallurgical industry, has been engaged in the research of iron ore beneficiation process in Daye, Hubei, Wuyang, Henan, Zhongshan, Fujian, Baiyunebo and Baotou. In the past 40 years, many great achievements have been made in the field of beneficiation of hematite, polymetallic ore and rare metal ore. He presided over the research on beneficiation technology of mixed iron ore in WISCO Daye Iron Mine, and developed a new process of low-intensity magnetic separation-high-intensity magnetic separation. After the production line constructed by this process is put into use, the annual processing capacity of mixed iron ore reaches 2 million tons, and the profit in the first four years is more than 2 1 10 thousand yuan. Participated in the research of "Comprehensive Utilization of Niobium Resources and Product Development and Application Technology in Baotou Steel" and won the first prize of National Science and Technology Progress Award 199 1. He has also won the titles of "National Model Worker", "May 1st Labor Medal" and "National Excellent Scientific and Technological Worker". 1996 won the honorary title of "Science and Technology Star of Hunan Province". However, he was not intoxicated with the achievements he had made, but still stuck to the test site of mineral processing, and made new breakthroughs in the new mineral processing technology and scientific research of niobium resources in Baotou Steel (further improving the grade and recovery rate of iron concentrate and reducing the impurity content), which made the mineral processing technology of Baiyunebo show a brighter prospect. Published papers and research reports 10, such as Experimental Research Report on Improving Iron Concentrate Grade and Recovery in WISCO Daye Iron Mine and Comprehensive Recovery of Iron from Bayan Obo Oxide Mine by Weak Magnetism-Strong Magnetism-Flotation, etc.
