Abstract:

Purpose. Predictive assessment of promising mineralization points and ore occurrences of copper, gold, silver and associated components at the Koktaszhal ore field.

Methodology. Analysis of literary and library materials. Reconnaissance routes to study the geological situation of the area. During the passage of the routes, samples were taken, their mineralogical study was carried out to determine the patterns of distribution of the main ore minerals and impurities. To determine the contents of useful components, phase chemical analysis, spectral analysis, and spectrographic aurometric analysis were used.

Findings. The materials and their analysis obtained as a result of research significantly expand the idea of the ore field under study. The main ore-forming minerals are chalcopyrite and bornite, in much smaller amounts chalcosine, pyrite, and molybdenite are present in the ores. The main oxidized copper minerals in decreasing order are malachite, chrysocolla, chalcanthite, azurite. Thanks to detailed geological, mineralogical, petrographic, and laboratory studies, promising copper-porphyry ore occurrences have been identified. The aureole patterns are spatially combined and drawn up with the mapping of mineral concentrations on them, which are recommended to be studied in more detail.

Originality. According to the results of the research and analysis, new promising points of mineralization and metallizing process were identified using the latest high-precision methods for studying ore-forming minerals of copper-porphyry deposits.

Practical value. Studying the mineralogy of the ore field allows determining the typomorphic features of minerals for the search and evaluation of mineral deposits as well as improvement of the complexity of the use of raw materials. The use of mineralogical research methods at the current level increases the efficiency of exploration, helps to search for new promising areas and deposits and, in general, increases the mineral resource base of Kazakhstan, which is one of the most important tasks of developing countries. The results of the studies can serve as the basis for the subsequent further study of the ore field, quantitative assessment of the prospects of resources, the choice of mining and beneficiation methods. The additional study of little-known copper-porphyry ore occurrences, the search for new deposits of copper, gold, silver and associated components are the primary task of their industrial development in modern technologies.
