摘　　要：兑卤—冷结晶法制取氯化钾工艺优点较为突出,但因工艺特性决定了收率控制的重要性。文章对兑卤—冷结晶法制备氯化钾过程中钾损失几个关键点进行了分析,并结合理论分析和生产实践对几个关键点的控制方法进行阐述。Mixing brine - cold crystallization method is the process of potassium chloride which has prominent advantages, but the process characteristic determines the importance of yield control. Several key points of potassium loss were analyzed in the mixing brine - cold crystalliza- tion process of preparation of potassium chloride and several key points were elaborated combined with practical and theoretical knowledge of production control methods.
