| Abstract/Notes | The monograph describes in detail a new ore-formation type—gold-platinum-metal titanomagnetite—using the Pudozhgorskoye deposit of complex noble-metal-titanomagnetite ores associated with a trap igneous formation as an example. The primary minerals are titanomagnetite (Ti-V-Fe) ores with associated Pd, Pt, and Au mineralization, associated primarily with copper sulfides. The ores are classified as oxide-like, low-sulfide ores. Mineralization is confined to the titanomagnetite horizon, occupying a strictly stratified position in a contrastingly differentiated gently sloping (10-15°) sheeted dolerite intrusion with a thickness of about 120 m. The mineral composition of the ore according to the primary paragenesis is titanomagnetite (TiO2 - 19.5%, V2O5 - 1.45%, FeO - 73.8%), augite (W038Fs23En39), plagioclase (Labradorite, andesine). The ores are medium- to densely disseminated. The exsolution structures are submicroscopic. Only titanomagnetite concentrate is released during enrichment. Content of ore: Feval - 28.9%, Ti02 - 8.14%, V205 - 0.43%, Cu - 0.13%, BE (Pd+Pt+Au) - 0.928 g/t. Ore reserves of category A+B+Ci+C2 are 316.7 million t, copper 411.7 thousand t, BE in ore of category P1 is 293.9 t. Ores are easily enriched, BE and Cu are extracted from enrichment tailings into sulfide concentrate. Institute of Metallurgy of the Russian Academy of Sciences has developed an energy-saving technology for continuous two-stage (reduction - electric smelting) electrothermal processing of titanomagnetite concentrate. The deposit is profitable for open-pit mining. Overburden rocks are a useful mineral and will be used as building stone for crushed stone production. The factual information provided covers all aspects of the object, from geology and technology to economics. The monograph is a reference source on various issues of studying and exploiting the Pudozhgorskoye deposit. This paper partially summarizes the material from 25 years of research by one of the authors, who began studying differentiated and layered intrusions in 1983 under the supervision of M.M. Lavrov. However, he first became acquainted with this type of differentiated intrusions (Koikarsko-Svyatnavoloksky sill), with the “stratiform” titanomagnetite horizon, while still working in production in 1974-1975. The idea to test titanomagnetite ores arose from gold—gold ore deposits tend to be found in areas of high-iron rock, which in turn have a higher regional Au background. As a member of the Mineralogy and Geochemistry Laboratory (headed by V.S. Kulikov), the author studied the distribution of gold in ore occurrences, various rock types, and host and concentrator minerals—pyrite, chalcopyrite, and arsenopyrite. Therefore, the BE discoveries were made while still studying gold ore occurrences. Using good exposure and core from the Kondopoga crew of 1974-1975, it was possible to quickly identify not only the presence of precious metal mineralization but also establish paragenetic controls and its position within the titanomagnetite horizon. This groundwork allowed for a systematic and thorough approach to the subsequent study of the Pudozhgorsk deposit. Interest in the Pudozhgorsky intrusion arose due to the overlap of its development area with the Burakovo pluton, on which M.M. Lavrov's group had focused its work since the fall of 1984. This allowed the collection and preservation of rich core material from 1950-1952, which served as the basis for future research within the framework of subsequent research projects of the Laboratory of Geodynamics and Metallogeny (headed by S.I. Rybakov and A.I. Golubev). An analysis of geological exploration materials stored in the archives revealed that the mineral composition of the ores and differentiated layers and horizons of the intrusion, its structural position, and geodynamic position had not been studied. The discovery of a new group of elements—Pd, Pt, and Au—in complex Fe-Ti-V ores raised questions about the conditions of their concentration, genesis, and extraction technology. From 1999 to 2002, while working on the federal project "New Sources of Platinum Group Elements" (supervised by A.I. Golubev), we were able to further study the distribution of platinum group elements within the intrusion's cross-section and along its strike, as well as their recovery rates. The idea of placer platinum content in the Onega terraces, linked to the erosion of noble metal-titanium magnetite ores, was tested. Within the framework of the work on the federal scientific programs "Gold of Karelia", "Platinum of Russia" (scientific director Corresponding Member of the Russian Academy of Sciences D.A. Dodin) and "ONZ-1", "ONZ-2" (Department of Earth Sciences, Russian Academy of Sciences - scientific director Academician D.V. Rundqvist) the issues of the genesis of mineralization were resolved, the structure of the deposit was deciphered, its geodynamic position and the age of the intrusion were determined, the idea of the connection of the deposit with rifting processes - the Ludicovian stage of activation of the Sumian rift - was substantiated. Recognizing the economic significance of the Pudozhgorskoye deposit for the Republic of Karelia and the timeliness of its further exploration and development, in 2004 the Institute of Geology assumed the obligation to perform contractual work to assess the overburden and prepare a feasibility study for its development. Completion of this work made the site attractive for investment. The research conducted over these years was based on the analytical base of the Institute of Geology and a diverse team of geologists and analysts. Complete silicate chemical analysis of rocks and minerals was performed by V.A. Kukina, R.F. Sarafanova, N.V. Pitkya, V.L. Utitsyna, A.I. Polischuk, G.K. Punka; quantitative spectral analysis - by G.D. Epishina, G.S. Ternovaya; X-ray fluorescence - by G.S. Ternovaya, N.A. Rakova. In a short time, A.N. Safronov carried out a huge amount of work on studying the mineral composition of rocks and ore using a TESCAN microprobe. N.K. Smirnova, T.I. Kuzenko, T.A. Antonova participated in the processing of primary materials and analyses. Invaluable assistance was provided with great responsibility and scrupulously by T.I. Kuzenko contributed to the X-ray photographs and initial text editing. Only thanks to the efficiency and expertise of O.O. Sokolan and N.E. Murzaeva were the figures and text of the monograph completed on time. M.M. Lavrov and O.I. Volodichev provided ongoing consultative assistance during the study of the Pudozhgorskoye deposit. A.M. Ruchev and V.I. Ruchev's consultations were instrumental in resolving a number of specific issues related to the deposit structure and autometasomatosis. Ivaschenko. The professionalism and commitment of each of these individuals made it possible to collect, process, and summarize the factual material on the Pudozhgorskoye deposit, for which the authors of this monograph express their sincere gratitude and respect. This work was conducted in accordance with the planned research programs of the Institute of Geology, Karelian Research Center, Russian Academy of Sciences, and on the topic "Assessment of the Prospects of New Sources of Platinum Group Elements (PGE) in the Republic of Karelia" as assigned by the Karelia Committee of Natural Resources, the federal program "Platinum of Russia," and the fundamental research program of the ONZ-2 RAS "Metallogenesis and Assessment of the Prospects of the Karelian Region for Large Complex Precious Metal Deposits." This monograph was published with the support of the Ministry of Natural Resources of the Republic of Karelia under the quotation application "Pudozhgorskoye Precious Metal Titanomagnetite Deposit." | ||
