Substantiation of Mineral Extraction from Man-Made Deposits

Abstract

Analysis of scientific publications of recent years has shown the need to further study the development of man-made mineral deposits in Ukraine. The main reasons for development of man-made deposits were considered, and the basic requirements for mining man-made deposits were formed, including: efficiency increase of mining operations; reduction of negative environmental impact on the region and restoration of land after industrial activity. Technology that made it possible to group dumps based on their formation is analyzed, which allowed to form clusters. They allow to determine the optimal technology for the development of man-made deposits based on the type of minerals to be extracted and the method of its formation. As a result of the study, the algorithm of making decision on the choice of optimal technology for the development of man-made deposits based on graphical data was developed, taking into account the type of minerals to be extracted, depending on the structure of the deposit and the specific features of its formation.

Simulation of Leaching Processes of Polymetallic Ores Using the Similarity Theorem

“…We use the predicted leaching data (Maltsev et al, 2018) obtained in the research (Maltsev, 2015) to determine the constant coefficients a and b, and tabulate these data (see Table 1).…”

“…Wide possibilities of applying this theory allow its use for solving the problems of motion of the laminar boundary layer in liquid. In this connection, the P-theorem becomes particularly important, which allows us to carry out a factor analysis of the physical phenomena inherent in the leaching process, thereby significantly simplifying the number of calculations in the model (Maltsev, 2015;Maltsev et al, 2018).…”
