| Abstract: The Dogai Coring Salt Lake, located in a depopulated area of northern Tibet, is of chloride type and contains high-grade potassium and lithium resources. A process route for concentrating low-salinity brines in alpine cold areas in winter has been established according to the natural conditions of the lake area. Following the process route, refined brine rich in potassium and lithium has been successfully obtained by using the two-step method of freezing and solar evaporation and the phenomena of supersaturated solubility of calcium sulfate during the brine evaporation and delayed precipitation of gypsum have also been analyzed. |
