Krasnojrskiy cluster - strategic development priorities rare metal industry Russia

Krasnoyarsk cluster based on Chuktukonskogo deposits of niobium-rare earth ores - a strategic priority of rare metal industry in Russia. The field belongs to rudnoformatsionnomu type rare-metal carbonatite weathering crusts. The ore zone of the deposit is a powerful plascheobraznuyu reservoir 3.5 km with a width of 800 to 1400 m and capacity up to 200 m. The mineral composition of ores: goethite, hydrogoethite, hematite, psilomelane, pyrolusite, bariopirohlor, strontsiopirohlor, tseriopirohlor, pyrochlore, fl orence monazite, tserianit. The elemental composition of REM (%): La - 29,64, Ce - 45,77, Pr - 3,96, Nd - 13,4, Sm - 1,68, Eu - 0,44, Gd - 1,35, Tb - 0,14, Dy - 0,58, Ho - 0,14, Er - 0,20, Tm - 0,02, Yb - 0,15, Lu - 0,04, Y - 2,45, yttrium - 7 20. Reserves of rare earth ores, approved by the State Reserves Committee of the Russian Federation (2007) make (th. т): 6639 (cat. C2), niobium pentoxide: 39.8 (content of 0.6 %), REOs - 486 (content of 7.3 %). The most acceptable pyro-hydrometallurgical ore processing scheme to obtain at different stages of niobium, rare earth, manganese, phosphorus, vanadium, iron products. Also developed two new technological scheme of ore processing: autoclave Nitrate and alkaline-acid preliminary magnetizing roasting. The calculation of the technical-economic indicators of development Culturescape deposits show high effi ciency of project horizon estimation 10 years. The strategic competitive advantages of creating a cluster of Krasnoyarsk rare metal industry are the presence of: a large mineral resource base of rare metals, scientific and industrial base for geological and technological research and support (Krasnoyarsk), the production base for processing low-radiation concentrates and construction of the plant rare metals ( Mining and Chemical Combine, Zheleznogorsk).
