Abstract
The melting in the system of aluminosilicate (granite) melt — fluoride salt melt at T = 800–1200˚C and P = 1–2 kbar was experimentally investigated. The data on the phase composition of silicate-salt systems and the character of the interphase distribution of ore components are presented. The partition coefficients of rare-earth elements between the granite melt and fluoride phase at 900–1200˚C, P = 1–2 kbar were obtained. It is shown that REE enrich the fluoride phase with respect to the silicate melt. Elements of the (V, Nb, Ta), (Ti, Zr, Hf) groups almost always prefer a silicate melt relative to fluoride.
