Preliminary Study on Low Potassium Original Brine Dissolved Ore Test in the Bieletan Mining Area of Cha'erhan Salt Lake
Taking shallow solid potassium salt as the research object,this article attempts to use low potas-sium original brine as the solvent to conduct field solid-liquid conversion experiments,and analyzes charac-teristics of mineral dissolution changes.The experimental results show that the water level in the experimen-tal area significantly increased during the experiment.After the experiment,the KCl content in the brine of the 6#brine extraction channel and the inflow water of the test pit increased,and the NaCl content decreased.The quality of the original brine was significantly improved,indicating that low potassium original brine can be used as a solvent to convert solid potassium salts in the area into liquid phase.Due to the saturation of low potassium original brine for the NaCl,and the dissolution process of potassium containing minerals will precipitate halite,Therefore,the skeleton of the salt layer will not be extensively damaged during the experiment,and it will not affect the brine extraction facilities.It is feasible to use low potassium raw brine as a solvent for solid-liquid conversion.
