Some aspects of the economic evaluation of technogenic deposits as a promising raw material in the steel industry

The main stages of the economic evaluation of mineral deposits and features of technogenic deposits assessment are considered. At the turn of XX-XXI centuries an integral part of the new thinking becomes the concept of sustainable social and economic development that meets current needs and preserve the quality of the environment and its ability to meet the reasonable and necessary needs of present and future generations. Rationalization nature management implies the need to study the problems of optimized interaction between society and nature and their solutions; efficient use of natural resources for production and non-production purposes; intensify the use of economic techniques for the prevention or elimination of pollution and other damage to the environment. Sustainable development (Engl: sustainable development - balanced, correct, uniform and balanced development) - it is a process of change in which the exploitation of natural resources, direction of investments, the orientation of technological development, personal development and institutional change consistent with each other and strengthen the current and future potential to meet human needs and aspirations. Thus, sustainable development - a development that does not contradict the continued existence and development of mankind. One of the major problems of human society is the problem of sustainable development of mineral resources, including metallic minerals, especially rare and valuable non-ferrous metals, with the growth needs of the metallurgy, machine-building industry and related areas of science and technology. Iron and steel industry, despite the increasing worldwide use of various technogenic materials, is developing in the twenty-first century. In connection with the development of aviation and space technology, electronics, etc., increased demand for many ferrous and rare metals and alloys of these metals with ferrous metals. Therefore, increase in the mineral resource base (MRB) of metallic minerals, especially rare and valuable non-ferrous metals, with the growth needs of the metallurgy, machine-building industry and related areas of science and technology is actual. Promising areas of growth MRB of metallic minerals are the activities on the development of complex and technological fields. Currently, a comprehensive assessment of accompanying mineral components contained in essential minerals, carried enough, and accumulated waste production of mineral raw materials are also used in small quantities. One of the reasons is the high costs of extraction of metals, comparable to the cost of traditional production of minerals, and even exceeding them. At the same time, reducing the number of viable reserves of ore minerals suggests the need for extraction of metals from complex ores and from industrial fields. In the development of technogenic deposits of non-ferrous and rare metals is possible to obtain a significant ecological and economic benefits. In the first place, the most important thing is the economic evaluation of technological fields. Geological and economic evaluation of tech-nogenic deposits begins with an assessment of contents scarce metals that allows to estimate the reserves / resources of metals and efficiency of the development of these objects based on the availability of industrial, high-margin technology, the dynamics of prices and demand for nonferrous and rare metals.
