The work aimed to develop a rational technology for processing ore from the Yoshlik deposit, taking into account the solution of issues of the integrated use of mineral raw materials and environmental protection, and the development of a technological scheme. To enrich the ore of the Yoshlik deposit, a combined gravity-flotation technological scheme was recommended, followed by sorption cyanidation of the pyrite concentrate. According to the results of research on the results of sample the ore of the Yoshlik deposit, it was revealed that pyrite flotation is required to enrich the ore. Without pyrite flotation, gold recovery is low from 52 to 68%, with the use of pyrite flotation, the recovery increase is up to 24%. The specified purpose of the work follows the need to solve the following problems: compilation of a literature review on the current state of enrichment of copper ores; study of the material composition of ore samples from the Yoshlik deposit; experimental substantiation of the influence of various factors on the concentration of ore. In the ore sample of the Yoshlik deposit, gold is unevenly distributed by size classes, the precious metal is concentrated mainly in sludge classes.
