1.Introduction to disciplines and majors
This subject was originally an authorized subject for the master's degree in mineralogy approved by the Academic Degrees Committee of the State Council in 1986. In 1998, the graduate subject and catalog were adjusted to mineralogy, petrology, and ore deposits.
Mineralogy, petrology, and ore deposits are all disciplines that study earth's matter. Mineralogy studies not only minerals produced naturally in nature, but also process minerals and artificial minerals, as well as mineral raw materials and mineral materials related to these minerals. Petrology studies all kinds of rocks produced in nature, while mineralogy is a discipline that studies the distribution, formation conditions and causes of mineral resources on which humans depend.
2. Training objectives
This subject can be awarded a Master of Science degree.
The recipient of the master of science degree in this subject should have solid and broad basic theoretical and systematic professional knowledge in mineralogy, mineral materials science, silicate physical chemistry, applied mineralogy, etc. The status, frontiers and development trends of this subject In-depth understanding, able to use modern scientific theories and methods, experimental techniques and methods and computer technology to complete scientific research or special technical topics, and have the ability to engage in scientific research, teaching and independently pay for specialized technology. Able to read professional literature, materials and write abstracts in foreign languages. There should also be a certain sense of engineering, economic development and market.
3. Research direction
The main research directions of this discipline include the following aspects:
(1) Mineral materials
From the perspective of mineralogy, study the synthetic process, structural structure, material composition and physical and chemical properties of various inorganic non-metallic materials; study the availability and processability of various natural non-metallic minerals and rocks, which are excellent in synthetic properties Inorganic non-metallic materials and constantly develop new resources; study the physical and chemical changes and damage mechanisms of various inorganic non-metallic materials during synthesis, processing and use, and research and develop new products.
(2) Comprehensive utilization of industrial solid waste and mineral resources
Industrial solid waste mainly includes comprehensive utilization of various ore dressing tailings, metallurgical slag, power plant fly ash, coal gangue and other industrial wastes. Study the use of these industrial wastes to manufacture various slurries, sintered materials, gelled materials and thermal insulation materials, new building materials, etc. At the same time, we also study industrial waste gas, wastewater treatment agents and treatment projects.
The comprehensive utilization of mineral resources mainly studies the recovery and utilization technology of valuable elements in ores and tailings.
(3) Mineral deposit and geological fluid research
Mineralogy studies the distribution, formation conditions and causes of mineral resources in the crust. The discipline applies geology, geochemistry, geophysics, and a variety of physical, chemical, and rock and mineral testing techniques to study deposit output characteristics and spatial distribution rules, structural ore-controlling rules, wall rock alteration, mineral symbiotic combination characteristics, ore-forming materials The source, the genesis of the deposits and the regularity of regional mineralization provide scientific information for expanding prospective resources. Fluid inclusions are paleogeological fluids enclosed in minerals during the formation of minerals and rocks. Their research content includes the types and characteristics of inclusions, temperature, pressure, composition and other parameters, revealing the geological environment of their storage, discussing the physical and chemical conditions of diagenesis and mineralization, and Sources of ore-forming materials; research on inclusions, halo, halo, salt halo, etc., to guide the deep and peripheral exploration of the mining area; identify gemstones, improve the performance of synthetic mineral materials, solve problems in the field of oil and gas fields and geothermal exploration, and help solve nuclear reactor cores The safety of nuclear waste storage addresses.
(4) Process mineralogy and industrial petrology
Process mineralogy includes mineralogical process mineralogy and metallurgical process mineralogy. Beneficiation process mineralogy mainly studies various data related to beneficiation process (such as material composition, content, chemical composition, intergrowth relationship between phases, differences in physicochemical properties, and particle size composition, etc.) as well as for beneficiation process research and production process Find the cause of the problem and propose a solution. The content of metallurgical process mineralogy research mainly includes the rational utilization of metallurgical raw materials and the quality of metallurgical products and the trial production of new products. Carry out a comprehensive study on the process mineral composition, content, particle size, microstructure and formation mechanism of raw materials and products such as artificial rich ore, slag, refractory materials, steel inclusions, continuous casting protective slag, etc., so as to propose the rational use of raw materials And the theoretical basis for improving product quality and optimizing the formulation process and program; in the trial production of new products, metallurgical resources are used to trial-produce high-value-added metal and non-metallic materials (such as titanium nitride, mullite and other refractory materials).
(5) Gemology and mineral modification
The main research is the identification of gems, artificial optimization, modification, artificial synthesis of gems and the artificial modification and application of physical and chemical properties of other natural minerals.
This subject is organized on the basis of the Department of Resource Engineering, and has experimental facilities such as mineral rock and ore deposit laboratory, mineral material laboratory, inclusion mineral laboratory, mineralogical laboratory, petrographic laboratory and so on
