Best available technologies of wastes processing in mining and metallurgical industries

Abstract

Mining and metallurgical industries are referred to high wastes productions. To decrease the damage to environment, progressive equipment and technologies are required. It was shown, that the modern approach to the environment protection should be based on implementation best available technologies (BAT). In the elaborated industry technical information BAT reference-book for the mining and metallurgical industries recommendation presented for utilization of main technological wastes of metallurgical production. A brief review of technologies presented, implementation of which allow providing practically complete processing of non-organic wastes, arising during raw materials mining and production of them ferrous metals. To choose the methods of construction and operation wastes utilization, one should be guided by recommendations, related to the thermal sterilization technologies for organic wastes as well as recommendations for utilization of organic wastes. It was noted, that the part of BAT reference book devoted to storing and disposal of production and consumption wastes is an evidence of high level of technologies used in Russia to realize the process. It was indicated, that in the BAT reference books the foreign experience of wastes utilization was not taken into account. Besides, a possibility to sterilize the wastes by thermal method in metallurgical furnaces was not also described. As a whole the application of the information presented in the BAT reference books, will allow to guide specialists of mining and metallurgical plants to choose best available technologies of handling with production wastes.
