摘　　要：针对大柴旦地区硼酸母液大量外排造成当地盐湖卤水和地下水资源遭到污染的现状,结合国内外硼酸母液处理技术,提出了该地区硼酸母液综合利用方案,即采用母液蒸发浓缩—冷却结晶—浮选分离的方法,达到回收硼酸、硫酸镁的目的,避免了资源浪费及环境污染。According to current state of boric acid mother liquor drained from boric acid production polluting underground water resources and salt lake brine,and processing technology for boric acid mother liquor at home and abroad,a comprehensive utilization program for treating the boric acid mother liquor in the area was put forward.The process included mother liquor concentration by evaporation,and cooling crystallization,and flotation separation.Boric acid and magnesium sulfate could be recovered by adopting the process,and resources waste and environmental pollution could be avoided at the same time.
