摘要
随着近年来国内高品位铝土矿资源的逐渐减少,低品位铝矿石的综合利用技术已广泛应用到工业化氧化铝生产中。但其杂质含量较高,致使国内部分地区的铝土矿生产的氧化铝含有较高的锂、钾等成分,长期使用会导致工业电解质中的锂盐和钾盐的大量富集,电解槽出现效率低、电耗高、难控制、稳定性差等现象。目前,高锂、高钾电解质体系先后在河南、山西等省区的电解铝厂出现,此电解质体系已经影响到该地区电解铝企业的正常生产。基于此,主要介绍河南永登铝业有限公司在应对高锂高钾复杂电解质体系过程中所进行的实践和探索,并就采取的措施进行分析和论证。
With in recent years domestic high grade bauxite resources gradually reduced, the comprehensiveutilization technology of low grade bauxite has been widely used in the production of industrial alumina,but its high content of impurities, resulting in parts of the country＇s bauxite production of alumina withhigh lithium, potassium and other ingredients, long-term use will lead to industrial electrolyte of lithiumand potassium accumulation, electrolytic cell appeared the phenomenon of low efficiency, high energy con-sumption, difficult to control, poor stability. At present, high potassium and high lithium electrolyte systemhas appeared in the electrolytic aluminum plant of Henan, Shanxi and other provinces, the electrolyte sys-tem has affected the normal production of the electrolytic aluminum enterprises in the region. Based onthis, this paper mainly introduced the practice and exploration of Yongdeng Henan Aluminum Co., Ltd. inthe process of dealing with the high potassium and complex electrolyte system, and the measures takenwere analyzed and demonstrated.
