Modeling of metal leaching processes in the disintegrator

One of the key problems of mining production is the involvement in the production of substandard metal-containing raw materials of technogenic origin. The problem of using substandard raw materials for traditional methods of enrichment is associated with the problem of strengthening the mineral resource base of metallurgy. Among the directions of extraction of metals from ores, the priority of the problem of waste-free production or the inclusion of waste products from the tailings of primary processing into use without restrictions on sanitary conditions is noted. The article substantiates the feasibility of implementing a new direction for the mining industry: involvement in the production of substandard metal-containing raw materials of technogenic origin by leaching in a high-speed disintegrator mill. The results of the state of the mineral resource base of non–ferrous metals are given. New data on the extraction and loss of metals in the process of ore dressing are presented. A decrease in the gap between the content in processing waste and in ore reserves was noted. It is shown that the total value of metals in waste is comparable to the value of potential mineral resources in the subsurface. The expediency of assessing the possibilities of technologies for the utilization of man-made reserves by modeling the processing indicators is substantiated. It is concluded that the problems of using mining waste should be solved in a single package by creating a technological cycle of extraction and processing of man-made waste, the use of which can make the development of technogenic deposits economically profitable. The purpose of research on theprospects of solving the problem concerned is to prove the possibility of extracting metals from man-made raw materials to the desired level which is achieved by using the method of mathematical modeling of metal leaching processes.
