Abstract

The distribution of lithium between aluminosilicate and alkali-alumina-fluoride salt melts in a granite system with the limiting contents of water and fluorine at temperatures of 700– 800° C and pressures of 10–50 MPa has been experimentally studied. It is shown that lithium is distributed in favor of the salt melt under all conditions. An increase in the water content in the system by more than 20 wt.% and a pressure from 10 to 50 MPa leads to a decrease in the partition coefficients of lithium between the salt and aluminosilicate melts by 2–4 times.
