摘　　要：晒制出合格成矿卤水的时间,是盐湖生产效率控制因素之一。试验研究了氯化镁存在对卤水蒸发影响。结果表明,在-18~35℃的温度范围内,氯化镁存在对卤水蒸发效率有影响,且温度越低影响越大。生产中有效去除镁离子,可以大大缩短卤水成矿时间,提高生产效率。The time of drying out qualified brine is one of the control factors of salt lake production efficiency. The effect of magnesium chloride on the evaporation of brine was investigated. The results show that the presence of magnesium chloride has an effect on the evaporation efficiency of brine, and the lower the temperature, the greater the effect, in the temperature range of-18 ℃ to 35 ℃. The effective removal of magnesium ion in production can greatly shorten the mineralization time of brine and improve the efficiency of salt lake production.
