硫酸法生产硼酸母液回收利用技术

The recovery technique of mother liquid in boric acid production process by sulfuric acid method

介绍了提高硼酸收率、解决母液回收利用问题的方法 ,并对硫酸法生产硼酸母液回收利用进行了介绍 ,该工艺采用母液蒸发浓缩—冷却结晶—浮选分离的方法 ,达到精制硫酸镁、回收硼酸的目的 ,避免了资源浪费及环境污染 ,成品硼酸的质量不受影响 ,副产品七水硫酸镁的质量达到部标各项指标要求 ,没有环境污染 。

New technique of mother liquid recovery in boric acid production process by sulfuric acid method is introduced.The technique including mother liquid vaporization-concentration,cold crystallization and float separation is adopted to recover boric acid and refine magnesium sulfate,finally raise recovery rate of boric acid and avoid resource waste and environment pollution.
