ABSTRACT At present, the main method used in China in the production of potassium carbonate is ion-exchange method. This method has such advantages as simple process, reliable technology, less investment, good quality and low cost. But some deficiencies still exist, address that the raw materials and resin utilization is low, the solution concentration after exchange is not high. In this paper, combine with the actual production, reference to the principle of continuous ion exchange process to improve the traditional ion-exchange process, the experiment has been performed to produce Potassium Carbonate? by the techniques of absorption with series three ion exchange columns and elution with series two ion exchange columns. In this issue, absorption with series three ion exchange columns and elution with series two ion exchange columns have been researched and experimented,and have been compared with single-column ion-exchange process in t
