The salifiable elemental behavior on concentration as well as the variation of brine chemical types and pH value have been revealed. Some conclusions were drawn:1.The main ionic evolutional direction of brine is incremental in the order:Ca²⁺→Na⁺→K⁺→Mg²⁺→Ca²⁺(cation) as well as CO₃^2-→HCO₃^-→SO₄^2-→Cl^-(anion). 2.In addition to the Separation of solid salt, the trace elements have a high degree of centralization in the final concentrative brine and the remnant brine after salt separation. More than 63 elements have been investigated in brine, such as K, Mg, B, Li, Rb, Cs, Sr, U, Th, Tr, D(²H), etc. Which have constituted a precious resources with comprehensive use.
