介绍了采用密实移动床吸附塔、以离子交换法从拜耳工艺溶液中提取镓的扩大试验结果。树脂吸附镓饱和以后，用特制的碱性络合淋洗剂淋洗。淋洗合格液经蒸发浓缩、冷冻结晶、氧化等工序处理后再进行电解，可获得产品镓，贫树脂经转型后可返回吸附工序再使用。本工艺流程简单，操作方便，试剂用量少，产品成本低，对环境无污染。镓吸附率可达60%～65%，淋洗率大于90%，电解回收率大于90%。
介紹瞭採用密實移動床吸附塔、以離子交換法從拜耳工藝溶液中提取鎵的擴大試驗結果。樹脂吸附鎵飽和以後，用特製的堿性絡閤淋洗劑淋洗。淋洗閤格液經蒸髮濃縮、冷凍結晶、氧化等工序處理後再進行電解，可穫得產品鎵，貧樹脂經轉型後可返迴吸附工序再使用。本工藝流程簡單，操作方便，試劑用量少，產品成本低，對環境無汙染。鎵吸附率可達60%～65%，淋洗率大于90%，電解迴收率大于90%。
