Extraction of useful components from ilmenite-titanomagnetite ores of Sikhote-Alin (Russia)

Abstract

In the south of the Far East of Russia, a new source of critically important metals (titanium and iron) has been discovered - ilmenite-titanomagnetite ores of mafic-ultrabasic rocks of the Sikhote-Alin orogenic belt. On the example of one of these massifs, Kokshaarovsky, the possibilities of decomposition of mineral raw materials are conducted with using hydrometallurgy methods are considere. The opening of the studied mineral raw materials was carried out by means of using ammonium hydrofluoride NH4HF2 and ammonium sulfate (NH4)2SO4 with subsequent complete transfer of useful components into solution. It has been established that the use of a mixture of these reagents makes it possible to more fully open titanium-containing rocks. The experience of deep processing of ilmenite-titanomagnetite ores will allow outlining the ways for the industrial development of complex deposits of the Far East.
