In the production process of salt lakes，lithium，potassium and other resource elements suffer significant losses during the evaporation and concentration processes in the salt field system.In order to study the distribution pattern of lithium in the salt field system，herein，we took the West Taijinar Salt Lake in Qaidam Basin of qinghai as research subject，and constructed the Computational Fluid Dynamics（CFD） model of the salt field system.Firstly，indoor simulated evaporation experiments were conducted and a CFD model was built to obtain key parameters such as the evaporation rate of brine and the diffusion rate of lithium ions.Then，the CFD model of West Taijinar Salt Lake was constructed to study the variation of lithium elements along different sections in different halogen production stages.Finally，the distribution laws of resource elements in different seasons were studied based on the CFD model，and the differences in the distribution of resource elements in salt pans in summer and winter were pointed out.The on-site sampling analysis results of the salt field indicated that the error in the distribution of lithium elements obtained from CFD simulation was below 2%，demonstrating that the constructed CFD model could accurately predict the distribution of lithium in the salt field system，which provided solod theoretical support for improving the recovery rate of resource elements in the salt field process.
Key words： West Taijinar Salt Lake; lithium-ion; CFD simulation; brine evaporation
