摘　　要：大柴旦盐湖含硼,卤水生产硼酸一般有两种工艺,一是传统的酸法提硼工艺,二是离子交换(树脂)提硼工艺,为减少硼在固相中的夹带损失,进行离子交换法从原卤水中和分离NaCl后溶液中提取硼的试验,硼的回收率达到了80%以上。There are two kinds of technological methods to produce boric acid by brines acid extraction method. One is the traditional acidic extraction,and the other is the anion exchange resin extraction method. In order to reduce the loss of boron in smuggling sofid,anion exchange resin was used to separate NaCl for recovery of boron. The recovery of the second method is higher than 80 %.
