Abstract
Potassium Khor-Biabanak is a rich source of magnesium, calcium, potassium, and sodium. In this research, we tried to separate and precipitation of their calcium and magnesium in the presence of other cations and anions using oxalic acid as a precipitator. Before the experimental phase, simulation of the reactions, and prediction of the results were performed using Stabalk modeling software. Based on the data processing of this software and also the obtained experimental results, the best molar ratio of oxalic acid to calcium and magnesium obtained for calcium separation from saline were 1.05: 1 and 1.25:1, respectively. The obtained analyzes showed that using this method, separation of 87% of calcium and 88% of magnesium from saline is possible and 95% and 94% purity for extracted calcium and magnesium oxalate salt are available, respectively.
