Traditional technologies for the development of ore deposits of the Dzhezkazgan deposit, including a standard set of geological and technical measures were able to stop the downward trend in the study of the characteristics of the mineral substance of useful components to a certain extent. But this effect can not last long. There is a need for a comprehensive analysis of the quality, relationship of composition, structure, physical properties and genetic characteristics of the mineral substance with the technological properties of minerals on the example of Dzhezkazgan deposit. The decision on introduction of new technologies is made on the basis of their detailed assessment on a set of technological, economic, technogenic and other factors important for mining and processing industry of the mountain region, its population and natural complex as a whole. Purpose of research. Study of interrelation of composition, structure, physical properties and genetic features of mineral substance with technological properties of useful components of Dzhezkazgan deposit. Research result. The results of the study make it possible to effectively make organizational and technological decisions for the correct choice of new technologies of the mining and processing complex. The peculiarity of the study is that the proposed method can be used in the fields of the mountainous regions of the North Caucasus. Summary. 1. Study of mineralogical characteristics of rocks containing three packs: quartz-carbonate rocks (PCM), quartz-siderite rocks, which are marking for the ore-bearing horizon (PS), mineralized rocks of near-contact ore zones (MZ). In laboratory studies, monofractions of bornite, chalcosine and Galena were isolated along the three lower horizons, and the chemical composition of impurity elements were determined by spectral analysis. 2. It is established that impurities in bornite, chalcosine Galena, such as Ag, Be, Bi, Cd, Co, Fe, Mn, Ti, Zr, gradually increase, and such as As, Ni, V, W, decrease, the content of the remaining elements is less than the sensitivity of the device. Various technological types and grades of ores are defined, the assessment of technological properties of raw materials that allows to define an effective way of processing of ores and indicators of extraction is carried out.
