Abstract

The article presents a comprehensive study of the Nukrakon deposit in the Central Kyzylkum, which is one of the largest gold-silver mineralization sites in Uzbekistan. Special attention is paid to the characteristics of ore deposits, their morphology, and the distribution of valuable components. The article also presents the results of detailed technological studies of various ore processing methods, including sorption cyanidation, flotation enrichment, tailings processing, and counterflow decantation. The analysis showed the high efficiency of cyanidation as the main method of extraction of noble metals, and the optimal combination of technological parameters of the process was established. The forms of silver and gold in ores, including native state, sulfide and oxide compounds, were studied. The most promising enrichment technologies were identified, allowing to achieve maximum extraction of valuable components at minimal costs. The data obtained allow us to recommend a combined ore processing technology for the industrial development of the deposit, using counterflow decantation and zinc dust cementation, which ensures a high degree of metal recovery at relatively low capital and operating costs.
