Howewer, overtapping of salt lake resources would also bring problems of destroying resources and polluting environment to the salt lakes for man made or natural forces.

High purity Magnesium oxide is prepared by Ammonia synthesis It has found in the experiment that the method is very effective in exploring salt lake resources of Qinghai province This method is simple, the quality of the product is rather steady, the content of Magnesium oxide has reached 998%～9995% and volumetric density is big or equal to 34%, it is suitable for industrial production

The level of exploitation of Qinghai Salt Lake resource was tentatively defined as thatit is still in the preliminary stage of sustainable development.

It is well known that the comprehensive utilization of the salt lake resources,which are the predominance mineral resources in the west of China,must base on the corresponding aqueous phase equilibria and phase diagrams.
