摘要
铝电解槽废阴极是目前铝电解生产最大宗的固体废弃物。分析了废阴极中的有用成分,综合论述了废阴极的处理现状。提出采用浮选和碱浸工艺可有效回收利用其中的炭和冰晶石。
Spent carbon cathode is the largest amount of solid waste in the aluminum electrolysis. By analyzing useful compo- nents in spent carbon cathode and discussing comprehensively treatment situation of spent cathode, that carbon and cryolite in spent carbon cathode can be recycled effectively with the flotation and alkali leaching technology has been put forward.
