Salt lakes are well developed in China with all hydro-chemical types. Carbonate-typed Zabuye Salt Lake is located in the interior of the Tibetan Plateau. The lake, at the latter period of salt lake evolution, is a coexistence deposit of solid and liquid which is of great economic value. Through isothermal evaporation of Zabuye Salt Lake brine at 15 and 25oC, we studied the concentration behavior of elements and the crystallization paths of salts. After comparing with carbonate-type and sulfate-type lithium salt lakes of their brine concentration rule and crystallization paths domestic and overseas, it can be concluded that the Zabuye Salt Lake brine has the unique crystallization path during evaporation. In the experiments, low evaporation temperature is appropriate for lithium concentration while high temperature for boron. Zabuyelite(Li2CO3) and potash were precipitated together during evaporation. It is easier to extract high-grade lithium carbonate at higher temperature. K is precipitated as sylvite at low temperature while as aphthitalite at high temperature.
