Annotation: The results of the technological study of a sample of primary copper-porphyry ore from the Sari-Chokki deposit are presented. Organic data on the chemical, mineral and granulometric composition of the ore are given. The copper content of the ore (Cu- 0.5%) is also gold (Au - 0.4 g / t) and silver (Ag -1.8 g / t). The ore is aggregate, with capillary and microwave textures, and its minerals are chalcopyrite and pyrite. The main mineral of copper is chalcopyrite. When BKK was used as a collector, the separation of copper in sulfide enrichment was 85-94%, and the amount of collective copper enrichment was 3.75-10.77%.

Keywords: copper-porphyry ores, grinding rate, collective flotation, accumulator.
