Abstract:
XXI century is the century of high technologies. Further scientific and technological progress, reaching the world level in quality and ensuring high rates of industrial production force the intensive exploitation of natural resources, among which the share of mineral raw materials accounts for more than 70%. Over the past 25 years, approximately the same amount of mineral raw materials has been extracted from the bowels of the earth as in the entire previous 100 years. In connection with a general decrease in the content of useful components in mineral raw materials, maintaining the achieved level of industrial production requires an increasing volume of raw materials. Under the current situation, the physical volume of extraction of mineral raw materials doubles every 30 years, and of fossil fuels every 15 years. The main trends in the complex processing of industrial waste from mining and metallurgical production are considered. The main sources of man-made waste formation and methods of their processing are analyzed. New technologies of waste processing developed by domestic and foreign researchers are presented. Special attention is paid to the solution of issues of ecology and environmental protection.
