Abstract
This article analyzes the theoretical and practical aspects of processing gold-bearing refractory ores and technogenic waste using pyrometallurgical methods. The study focuses on interfacial equilibrium, redox reactions, and the distribution of noble metals in the slag-stein-metal system during high-temperature smelting processes. The article emphasizes the importance of optimizing the composition of the charge and identifying the technological factors that ensure efficient extraction of gold and silver from the matte produced during the smelting process. The article discusses the possibilities of increasing the selective extraction of metals using modern pyrometallurgical approaches, including collector smelting, control of the reducing environment, and the use of additional components. The results of the study show that by optimizing the preparation stages of raw materials, scientifically selecting the composition of the charge, and managing the smelting processes, it is possible to increase the degree of extraction of rare metals and minimize losses. This allows for improved technological efficiency and the rational use of technogenic resources.
