Study on the Solid-Liquid Phase Equilibrium of the Calcium-Containing Brine System

It is well known that the comprehensive utilization of the salt lake resources successfully must be under the guide of the corresponding aqueous phase equilibria and phase diagrams. The researches on phase relationships of the calcium-containing brine system are essential to promote the comprehensive development and utilization of the relative salt lake resources discovered in our country at present years. In the paper, the progresses on the phase equilibrium of calcium-containing brine systems corresponding to sea water system, carbonate system, borate system and calcium-lithium coexisted system around the world were presented. The problems existed recently and the new trends in the future were also carried out.
