Аннотация
The melt in the alumosilicate (granite) melt–molten fluoride salt system is experimentally studied at Т = 800–1200°С and Р = 1–2 kbar. The data on the phase composition of silicate–salt systems and the character of the phase distribution of ore components are presented. The coefficients of the distribution of rare-earth elements (REEs) between the granite melt and the fluoride phase at 900–1200°С and Р = 1–2 kbar are obtained. It is shown that the REEs enrich the fluoride phase relative to the silicate melt. The elements of the (V, Nb, Ta) and (Ti, Zr, Hf) groups almost always prefer a silicate melt to a fluoride melt.
