Introduction to disciplines and majors

The processing and utilization of minerals (metals, coals, non-metals) have a history of thousands of years. Mineral processing engineering is a discipline that uses the principles and methods of physics, chemistry, physical chemistry, and biochemistry to process and comprehensively utilize mineral resources according to the differences in the nature of mineral raw materials in nature.

Mineral processing engineering is a second-level discipline that belongs to the first-level discipline of mining engineering. After decades of construction, the discipline of mineral processing engineering has developed from a single beneficiation engineering technology that provides raw materials and fuels in metallurgy, energy, and chemical industries, to a development that covers beneficiation engineering, comprehensive utilization of resources, mineral materials, powder engineering, and mineral deep processing. And fine processing (such as clean coal technology, mineral metallization direct reduction technology), environmental pollution prevention and other new disciplines of engineering technology, mineral processing technology tends to be efficient and clean, and mineral separation methods tend to diversify, Focusing on the comprehensive utilization and development of mineral resources, computers have been widely used in various fields of mineral processing engineering. Mineral processing science and technology is of great significance for my country to carry out comprehensive utilization, save energy, reduce environmental pollution, and promote economic development. It has become one of the leading technologies for implementing sustainable development strategies.

The mineral processing engineering major was officially approved as a doctoral program in 1995. The major has always attached great importance to teaching research, carried out in-depth teaching reform, continuously improved teaching quality, and has a high level of teaching. He has undertaken and completed a number of key scientific research projects including the National Natural Science Foundation of China, national key research, and provincial and ministerial levels, and many have reached international or domestic advanced levels. Especially in the past two decades, it has continuously explored new fields and reformed majors at home and abroad, combined with the difficulties of this discipline and international development trends, and conducted in-depth theoretical and applied research. It has formed its own characteristics and advantages in scientific research and discipline construction. , And occupies a certain position in the field of mineral processing.
