| Abstract: | 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. |
