With the proposal of"dual carbon"goal,the application of lithium in the field of new energy materials has re-ceived great attention,and the demand for lithium has shown explosive growth.The world's lithium resources are mainly composed of ore lithium and salt lake lithium.Salt lake lithium has become the focus of future lithium resource development because of its large reserves,and therefore the sulfate type salt lake,which accounts for the largest proportion,has become the focus.Due to the significant difference in the composition of salt lake,and the special properties of sulfate type salt lake,lithium has multiple crystalline forms in the evaporation stage of saltpan and causes losses,which increases the difficulty of effective enrichment of lithium.The results of evaporation experiment of lithium-rich sulfate salt lakes were summarized,the law of crystallization salt evolution during evaporation based on the phase diagram was analyzed and summarized,with a fo-cuses on the concentrated state of lithium and the crystalline form of lithium,providing reference for the development of lithium resources in sulfate salt lakes.
