The task of the tests was to study the material composition in order to develop a rational technology for the enrichment of porphyry copper balance and off-balance ores of the Yoshlik I and Kalmakyr deposits to obtain collective, copper- and molybdenum-containing concentrates, finished products in the form of copper, molybdenum and pyrite concentrates. The material composition of ore samples was studied using spectral, chemical, assay, granulometric, phase, rational for gold and silver, mineralogical, and other types of analyses. Due to the absence of significant bonds of gold with pyrite, there is no expediency to carry out extensive studies of the hydrometallurgical processing of pyrite concentrates. It is possible to set up a basic experiment to determine the proportion of cyanidated gold. When processing ore raw materials enriched by flotation, not only various flotation reagents-collectors, technological parameters, but also the grinding size and material composition of the ore are important for obtaining a concentrate, since grinding the ore to the required size is about half the cost of obtaining a concentrate.
