This article is devoted to the additional extraction of valuable components from the waste tailings of the AMMC copper processing plant. The mineral composition of the waste tailings of the CCP is mainly represented by quartz, feldspars, sericites and, in a subordinate amount, mafic and secondary minerals. Pyrite is the most widespread ore mineral in the waste tailings of the CCP. Chalcopyrite, sphalerite, galena, molybdenite, and iron oxides are also noted. The copper content in the selected spot samples from tailings after chemical analysis averaged 0.139%. A sieve analysis was carried out to determine the granulometric composition of waste tailings, the distribution of valuable components by size classes. On the basis of the obtained results on the study of the material composition, flotation of tailings of the CCP AMMC was carried out with recleaning of the main flotation concentrate. During tailings flotation with one recleaning of the main flotation concentrate, the extraction of copper and molybdenum into the total concentrate is 56.8% and 63.8%, respectively.
