Technogenic impact on the environment during leaching

Abstract

The results of the analysis of the theory and practice of leaching metals from substandard raw materials are presented. A brief historical reference is given on the leaching of metals from experimental leaching in the middle of the last century to industrial development in modern times. The direction of combining traditional and innovative technologies within a single technological process is formulated. The mechanism of underground block leaching of ores is described. A complex method of multi-factorial assessment of the existing natural and man-made factors of development is proposed. The parameters of the proposed technology and some aspects of its application are substantiated. Using the method of engineering forecasting, the prospects for leaching metals from substandard raw materials are assessed. The main results of the development of underground leaching of metals from sub-standard raw materials and the prospects for improving the method with the rational combination of underground leaching technologies with traditional mining technologies are formulated. It is concluded that the leaching of metals from substandard raw materials has prospects for development.
