RARE-METAL POTENTIAL OF PLACER DEPOSITS AND WEATHERING CRUSTS OF THE RUSSIAN ARCTIC

Rare-metal deposits of placers, weathering crusts (saprolite) and mining tails have significant raw material potential due to significant volumes of natural and dump rare-metal deposits, their high profitability, rapid return on investment and technological availability of enrichment. The Arctic zone of Russia contains the following natural and dump rare-metal deposits: loparite placers of the Lovozero massif, dumps of apatite ores of the Khibini deposit group, baddeleyite dumps of the Kovdorskoye deposit (the Kola Peninsula), ultra-rich hypergenically altered sedimentary ores of the Tomtor deposit and gold-rare metal dumps of the Kular range (Yakutia), rare-metal-titanium placers of Salekhard and Timan, tin-bearing ores of Chukotka and Yakutia, which contain niobium, tantalum, indium and scandium as admixtures. Natural placers, weathering crusts and dumps in a short time can provide the needed raw materials for Russian rare-metal industry.
