Yakovenchuk NEW DATA ON REE RESOURCES OF THE MURMANSK REGION Re-estimation of known REE-deposits in the Murmansk Region has shown that the Afrikanda REE-Ti-Fe deposit, Alluaiv REE-Zr deposit, Jumperuaiv and the Big Pedestal Zr-REE deposits, Kovdor and Vuorijarvi carbonatite deposits as well as Khibiny apatite deposits are the primary objects for technologic- economic estimation. The technological scheme of these deposits exploitation should use results of three­ dimensional mineralogical mapping allowing to optimise selective mining of complex polycomponent ores. Comparison of existing ore processing schemes for apatite, rinkite, titanite, loparite, eudialyte, baddeleyite and zirkon has shown the possibility to use the sulfuric acid for all these cases to obtain REE oxides and a lot of useful by-products, in particular, titanyl sulphate for manufacturing of Ti-containing pigments, hardeners and sorbents. Keywords: REE, apatite, titanite, rinkite, loparite, baddeleyite, eudialyte, zircon, Kovdor, Keivy, Lovozero, Khibiny, Kola alkaline province, Murmansk Region. Authors Aya V.
