Research on Natural Evaporation Salt Field Technology of Qinghai Potassium Mine Brine
The main salt mining area under study is located at the Cha'erhan Salt Lake.The focus is on analyzing the reasonable development and utilization of potassium mine brine within this area,and effectively utilizing phase diagram analysis and experimental exploration to summarize the natural evaporation salt precipitation rules of potassium mine brine.After experimental analysis,it was found that under the application of traditional direct beach drying methods,the potassium loss rate in salt is very high,leading to a sharp increase in the content of sodium chloride in potassium salt products.It was also found that in most potassium ore products,potassium makes up 50%to 59%of the total as sodium chloride,while about 41%is primarily present as carnallite.To this end,in order to organize a more efficient brine mixing salt field process plan,the main analysis in this experiment is to use all potassium ions to precipitate in the form of carnallite,in order to reduce the content of sodium chloride to the minimum.
