It represents the national level in the research fields of mining, mineral processing, nonferrous metallurgy, process mineralogy, magnetic materials, industrial explosives and mineral processing equipment.

There are 1 technical innovation centers, 1 professional research institutes,1engineering design institutes,1technology industry companies and 3 directly affiliated factories. National Engineering Technology Research Center for Comprehensive Utilization of Metal Mineral Resources, National Engineering Research Center for Non-pollution Nonferrous Metal Extraction and Energy Saving Technology, National Magnetic Material Engineering Technology Research Center, National Nonferrous Metal Quality Supervision and Testing Center, and National Nonferrous Metal Commodity Inspection Laboratory. The academic organizations relying on the Institute include China Engineering Blasting Association, Mineral Processing Academic Committee of China Nonferrous Metals Society, Mineral Processing Academic Committee of China Mining Association and China Mineral Processing Information Network.

The Institute has 2,300 employees, including 3 academicians of China Academy of Engineering and more than 300 technicians with senior titles or above. Have the right to award master's degrees in mining, mineral processing, nonferrous metallurgy, material science and mechanical design and theory. Since its establishment, the Institute has completed more than 4,500 scientific research projects, obtained more than 2,500 scientific research achievements, won more than 80 national scientific and technological awards, won more than 800 provincial and ministerial scientific and technological awards and won more than 200 national patents.

The focus of the research institute is to carry out process research, equipment development and engineering design closely around metal mines and non-metal mines. In nonmetallic minerals, its basic contents involve mine reclamation, clean beneficiation, high-efficiency crushing and energy-saving technology, as well as the treatment and utilization of "three wastes". According to the specific situation of non-ferrous mines, carry out engineering research on related technologies, processes and key equipment, solve the pollution problem of mine industrial waste and smelting process, reduce industrial energy consumption, make China's non-ferrous metal industry production technology gradually reach or approach the world advanced level, and promote the sustainable development of non-ferrous metal industry; In terms of comprehensive utilization of resources, we will focus on developing complete sets of new technologies and equipment for comprehensive utilization of mineral processing and metallurgy, and new technologies and equipment for energy saving and consumption reduction, and continue to consolidate and maintain our advantages in mineral processing engineering, nonferrous metal smelting, environmental engineering, metallic materials, nonmetallic materials and other fields.

New achievements have been made in the development of new equipment. The research institute completed the project of "Development of PA 100 120 crusher with low external movable jaw and large crushing ratio", and applied the random fuzzy theory of crushing force distribution, the dynamic balance theory of mechanism and the simplified model of line contact four-bar variable-length rod crusher to innovate a crusher with independent intellectual property rights, novel structure and excellent performance. Compared with the traditional jaw crusher with the same specification, the production capacity is increased by more than 15%, the energy consumption is reduced by about 15%, the service life of jaw plate is increased by more than 2 times, the height of the whole machine is reduced by 16%, and the feeding height is reduced by 37.5%. The technical performance of this machine has reached the international leading level, and it is the largest external jaw crusher at present, creating a good performance.

GJ5×2 large-scale double-tank high-intensity stirred ball mill (peeler) is a new type of continuous ultrafine grinding (peeler). It is characterized by large specifications, high stirring speed, strong superfine grinding (peeling) process, high efficiency and fine product granularity; The working mode is continuous, and the agitator is impeller type, which has strong mixing effect. Wear-resistant lining is used for wearing parts such as tanks and mixers, which will not pollute materials. Based on these characteristics, the equipment can be used for ultrafine grinding (stripping) of kaolin, heavy calcium carbonate, mica, barite, wollastonite, iron oxide red, magnetic materials, alumina, talc, Yingshi, zircon sand, silicon carbide, dickite, illite, porcelain stone, bentonite and other industrial minerals. Especially in the case of continuous production in large-scale superfine material factories. This machine has been widely used and achieved good results.

Based on the long-term accumulation in the comprehensive utilization of mineral resources and the scientific development and application of ultrafine functional materials, the Institute independently developed a variety of functional ecological mineral materials with antibacterial and magnetic therapy health care functions to meet the needs of human health and the environment. Environmental-friendly tourmaline minerals are selected, and through special processing technology, the particles are distributed in submicron narrow size, with good dispersibility and good matching with other components in chemical fiber, paint and coating; Then through nano-film deposition technology, adding heat-sensitive valence-changing elements, the particles are chemically coated and doped, and finally the particles are spherical and regular, and a large number of free radicals are generated on the surface, which makes the powder have extremely high surface activity, which is the perfect embodiment of the functional design concept of products in advanced material preparation technology.

In recent years, Beijing Research Institute of Mining and Metallurgy has successfully developed an externally heated φ2500 rotary calciner for kaolin calcination, and successfully put it into operation in Shanxi Datong Changan Kaolin Co., Ltd. to produce coated calcined kaolin, successfully solving the problem that high-quality kaolin calcination depends on imported equipment and technology.

Since its establishment, the research institute has established a high-tech industry with its own scientific and technological achievements, and scientific research and scientific and technological industry have developed harmoniously. In-depth research has been carried out in the field of non-metallic minerals, and many new technologies, new processes and new equipment have been developed. With the promulgation of the national medium and long-term scientific and technological development plan, the Institute will continue to implement the Scientific Outlook on Development and make contributions to the economic development and industrial scientific and technological progress of China.
