Abstract: The paper justifies the prospects for processing low-grade man-made raw materials, represented by waste from the extraction and processing of chalcopyrite ores and mineralized industrial waste water, using methods of extraction, sorption, and cementation of copper and zinc. An overview is given of modern research methods and achievements in the field of hydrometallurgical processing of low-grade raw materials with copper and zinc extraction. The latest developments are discussed in the field of synthesizing selective extracting agents, optimizing technological parameters, and combined technological schemes. Particular attention is paid to the results of experimental tests demonstrating the efficiency of various extraction methods for specific types of raw materials. Modern challenges and prospects for the processing of low-grade and man-made raw materials are identified, in particular, the issue of sulfurous waste liquor disposal. The results of an economic and technological comparison of the extraction method with the conventional sorption and cementation processes are presented, demonstrating its high competitiveness and efficiency of technological application.
Keywords: man-made raw materials, processing waste, mineralized liquors, dry residue, extraction, sorption, cementation, technical and economic comparison
