METHOD FOR RECOVERING AN ELECTROPOSITIVE METAL FROM A METAL CARBONATE |
摘要 |
A method recovers an electropositive metal from a metal carbonate. In the method, hydrogen and halogen are combusted to form hydrogen halide. The solid metal carbonate is converted into metal chloride by a gaseous hydrogen halide. In an electrolysis, the metal chloride is decomposed into metal and halogen. The halogen produced in the electrolysis is led out of the electrolysis for combusting. Preferably, the hydrogen halide is produced by combusting the hydrogen and the halogen and the metal carbonate is converted into metal chloride in a fluidized bed reactor. Preferably, lithium is used as the metal. |
