REVIEW OF THE PROCESSING OF MINERALS AND TECHNOGENIC SULFIDE RAW MATERIAL WITH THE EXTRACTION OF METALS AND RECOVERING ELEMENTAL SULFUR BY ELECTROCHEMICAL METHODS

摘要

Due to the economic necessity of complex processing of poor, low-quality and inaccessible raw materials, as well as the production of metals from these ores of products with high added value, there is a problem of a complex study of the electrochemical behavior of metal sulfides in various environments, generalization and systematization of this material, the conclusion of General laws that allow predicting the behavior of these materials in non-stationary conditions.The review presents various methods of processing sulfide raw materials of both mineral and man-made origin.The world experience of using various technologies for extracting metals from sulfide ores and materials with the accompanying extraction of elemental sulfur is considered, which allowed us to choose the best method for electrochemical research of metal sulfides to simultaneously obtain metals with the extraction of elemental sulfur.
