Nb REE ore deposits related to weathered carbonatite within the Tomtor massif northern Siberia contain the world9s largest carbonatite related concentrations of Nb and REE Despite its remote location economic exploitation of the deposit was made possible by the discovery of rich Sc REE Y Nb ore The 300 km 2 Tomtor massif is a ring complex in which
Review report on the manuscript In situ crystallization and continuous modification of Cr spinel in the sulfide poor PGE ores in the Upper zone of the Norilsk 1 intrusion by Ivan F Chayka et al Manuscript ID 796686 submitted for publication to Minerals MDPI
She defended a PhD thesis entitled Geology and origin of Cu ores of the Chiney Massif in 1989 and Doctor thesis Evolution of trap magmatism and Cu Ni PGE deposits of the Noril sk area in 2012 She was awarded by the Special Price of Russian Academy of Sciences for her study of ore deposits of Eastern Siberia in 2015
The following features inter alia suggest the ores to be of sedimentary diagenetic origin very thin lamination in the ores parallelism of the orebodies with the primary laminations in the
Magnetite Chemistry by LA ICP MS Records Sulfide Fractional Crystallization in Massive Nickel Copper Platinum Group Element Ores from the Norilsk Talnakh Mining District Siberia Russia Implications for Trace Element Partitioning into Magnetite
The Noril sk ores are characterized by a wide variety of minerals species greater than400 in particular platinum group minerals PGMs Genkin et al 1966 Genkin et al 1969Begizov et al
Relative to Noril sk Ni Cu PGE sulfide ores the Siberian native Fe basalts are enriched in the PPGE relative to the IPGE but exhibit Ru enrichments The size of ore minerals is 30 1 µm
These ores are thought to form via various processes including 1 crystallization differentiation and accumulation of ore minerals such as apatite magnetite and perovskite Brod 1999 Jiang et al 2004 2 partitioning of REEs and rare metals into the carbonatitic magma during extreme fractionation of a carbonated silicate magma or
The state of the mineral resource base of solid mineral deposits MRB SMDs of the Russian Federation currently necessitates urgent action to effect a significant increase in quality and volumes of regional forecasting and estimation of geological exploration work in weakly studied territories of Siberia and Far East with a special attention to Arctic regions
Siberia encompasses most of northern Russia with a climate ranging from humid continental in the south to subarctic in the north Though its population growth has ceased Siberia remains economically significant for Russia due to its natural resources of gas coal petroleum timber and minerals
The particular dissemination of the minerals and intergrowth of the mineral species cause problems for the enrichment of these ores Kuzmin et al 2006 This essentially complicates ore processing as compared to the ores from the Bayan Obo deposit China which also are ferruginous but unlike the Chuktukon ores they do not contain any
Mineralogical and chemical zonations observed in massive sulfide ores from Ni Cu platinum group element PGE deposits are commonly ascribed to Siberia Russia Implications for Trace Element Partitioning into Magnetite from Cu poor MSS to Cu rich ISS Based on textural features and mineral associations four types of magnetite
The aim of this research was to study the rare earth REE minerals in ooidal ironstone deposits of the West Siberian basin and the Turgai depression

We document mineral and chemical variations in the ore types of the Ni Cu PGE deposits from Noril sk polar Siberia Russia offer an exceptional opportunity to investigate the behavior of TABS during fractional crystallization of sulfide liquids and PGM formation as the primary features of the ore bodies have been relatively well
Problems related to the processing of mineral raw materials from Siberia molybdenum tungsten lead and gold containing ores and concentrates are reviewed
Review report on the manuscript In situ crystallization and continuous modification of Cr spinel in the sulfide poor PGE ores in the Upper zone of the Norilsk 1 intrusion by Ivan F Chayka et al Manuscript ID 796686 submitted for publication to Minerals MDPI
The highest grade ores are natural Nb and REE concentrates The total REE content in some layers is >10% The morphologic features of the highest grade phosphate ores from the northern part of the Burannyi site were studied The ore forming minerals belong to the pyrochlore group crandallite group goyazite and monazite Ce
