Currently, metallurgy is understood as that area of science and industry that deals with the production of metals (sometimes alloys) from ores and other materials and the purification (refining) of the crude metal or alloy.
An important task of our time is the rational use and extraction of metals from ores based on the use of waste-free technological processes.
The integrated use of ores and concentrates is the most important condition for the further development of metallurgy. It ensures high rates and level of development of the national economy.
Integrated rational use of raw materials is their effective processing with the extraction of all valuable components, the completeness of which is determined by the current level of development of science and technology, using processes that do not create emissions of harmful substances into the environment and do not disrupt the existing circulation of substances in nature.
At the UNESCO international conference, it was recognized that the integrated use of raw materials is a science-based strategy for the development and protection of subsoil throughout the world.
The future of metallurgy is the transformation of elements. This is a whole branch of industry - radiation metallurgy, which will be engaged in the production of rare chemical elements from more common ones (I.P. Bardin).
The first scientific metallurgist was Agricola (1494-1555, who studied metallurgy at European factories. In 1556, his first book on metallurgy and mining, “De Re” , was published. Mtttalica ", but the scientific level of presentation of metallurgy issues in it was very low.
Discovery by the great Russian scientist M.V. Lomonosov (1711-1765) the law of conservation of mass of substances in chemical reactions (1748) made it possible, on the basis of this law, to outline methods for extracting metals from ores at a higher scientific level.
M.V. Lomonosov became the founder of scientific metallurgy and the author of the first book on metallurgy in Russian. His “First Foundations of Metallurgy or Mining” (1763) is an outstanding work in the history of metallurgy and chemistry. Of great importance in the development of theoretical metallurgy was the discovery of Acad. G.I. Hess (1802-1850) law of constancy of the sums of heat of reactions.
In 1834, M. Faraday (1791-1867) discovered the laws of electrolysis, which are the basis for the processes of electrolytic production and refining of metals.
A great achievement of world science was the creation of D.I. Mendeleev (1834-1907) in 1869 of the periodic table of elements.
The fundamentals of the theory of metallurgical processes in metallurgy were developed by Acad. N.N. Beketov (1826-1911). The theoretical foundations of metallurgy were further developed in the works of such scientists as D.K. Chernov, N.S. Kurnakov, M.A. Pavlov, N.N. Karnaukhov, A.A. Baykov, P.P. Fedotiev, G.G. Urazov, V.Ya. Mostovich, V.A. Vanyukov and many others.
