There are abundant resources in Dabasunnor salt lake in Xinjiang Province, with high exploitation and utilization value. The occurrence characteristic of rare element strontium and selenium has a direct impact on the development and utilization of products rich in strontium and selenium extracted from brine. It is very important to study the characteristics of strontium and selenium in brine to solve the problems in production. In this project, strontium and selenium in Xinjiang Dabasunnuoer Salt Lake will be taken as the research object, and the distribution, occurrence characteristic, enrichment regularity and thermodynamic properties of strontium and selenium in brine will be studied in detail. The distribution of strontium and selenium in the mining area will be explored. The occurrence characteristic of strontium and selenium in brine will be studied by various means, and the influence factors will be discussed. The migration and transformation rules of strontium and selenium will be clarified. The thermodynamic mechanism of brine mineral equilibrium will be discussed. The strontium and selenium in the product will standard, stable and controllable. These studies will provide a theoretical basis for the full utilization of trace elements in brine resources and the development of rich strontium and selenium salt industry.
