China's salt lake resources are mainly distributed in Qinghai, Tibet, Xinjiang and other provinces. However, because the salt lakes in these provinces are often sparsely populated, infrastructure is not perfect, and energy supply is insufficient, it has brought serious constraints to the development and utilization of these resources. At present, the devices for extracting minerals in brine mainly include evaporation crystallization method, precipitation method, salting out method, carbonization method, flotation method, extraction method, ion exchange adsorption method, calcination method, membrane separation method and the like. In order to save energy and reduce the requirements for infrastructure, the existing production process uses natural beach drying and evaporation crystallization, but the sun exposure time of Rizhao Beach often reaches 3 to 6 months, which severely limits the improvement of production efficiency. However, the industrial evaporative crystallization method is not suitable for direct application in the salt lake area due to its huge energy consumption, and the promotion of brine extraction and comprehensive utilization technology is also limited. Therefore, it is particularly important to seek a simple, efficient and energy-saving extraction technology.
