摘　　要：本文介绍了氯化冶金工艺分离金属元素的原理,并结合氧化铝生产产生的赤泥特点,围绕碳矿比、氯化方式、沸点温度、通气方式等因素对氯化分离含铝原料中的有价金属进行技术论证,提出了初步试验流程方案.最后,通过一组实验室试验,验证了金属氯化物的分离效率〉60%,回收率〉50%的目标。This paper introduces the principle of separation of chlorinated metallurgical processes of metal elements, combined with the characteristics of red mud in alumina production generated around the carbon ore ratio, chlorinated way, the boiling temperature, ventilation and other factors on the separation of aluminum-containing raw materials are chlorinated divalent metal technical feasibility studies, preliminary testing procedures proposed program. Finally, a set of laboratory tests to verify the efficiency of the separation of the metal chloride〉 60% recovery rate of 〉50% target.
