THE PIZHEMSKOYE TITANIUM DEPOSIT IS A NEW OBJECT OF THE NEAREST DEVELOPMENT IN THE ARCTIC ZONE OF RUSSIA

The Pizhemskoye titanium deposit (Middle Timan) has become one of the most attractive deposits for the industrial development in Russia as a result of the successful protection and approval of reserves at the State Reserves Committee (November 2020). 60 years have passed since the first finds of titanium mineralization in the basin of the Pechora Pizhma and Umba rivers by the thematic teams of the Ukhta Geological Exploration Department and the Komi branch of the Academy of Sciences, and now the deposit is considered one of the largest in Russia and the World. Together with the Yarega oil-titanium deposit, they contain up to 80% of the reserves and predicted resources of titanium in Russia. Timan becomes the largest raw material base of titanium in the world, the intensive development of which is possible for several hundred years. The article highlights the geological structure of the Pizhemskoye deposit (revealed a cellular, bowl-like structure of ore bodies); material and complex polymineral composition of ores; the Neoproterozoic age. The author proves the hydrothermal-metamorphogenic genesis of the ores, considers the sources of the mineral matter and solution of the technological scheme for processing refractory ores. The Pizhemskoye deposit is classified as a new pseudorutile-leucoxene-quartz subtype of primary metamorphogenic deposits.
