Over the past decades, due to the decrease in the quality of mineral raw materials from developed deposits, the share of gold extracted from refractory ores has increased, the effective processing of which requires the development of more complex and combined schemes that ensure the most complete extraction of gold. For the same purpose, in 2019, Navoi Mining and Metallurgical Combine (NMMC) successfully launched a workshop for roasting sorption cyanidation tailings during the processing of gold-bearing ores from the Kokpatas and Daugyztau deposits. At this stage, the NMMC specialists face the task of intensifying and optimizing the roasting process. This paper briefly presents the results of a detailed study of the effect of temperature on chemical transformations occurring during roasting of sorption cyanidation tails, carried out in order to identify the reasons that prevent the disclosure of gold particles during roasting and its encapsulation.
