Abstract:
    This invention provides a method for extracting Al and iron from a ferric gibbsite, which grinds and dissolves the ferric gibbsite then carries out rough and fine separation-washing to the red mud and sends the refined liquor to the resolving plant to separate AlOH and bake it to get A10. The red mud is matched with recovery coal and burning coal to be dried and baked then to be ground and selected magnetically to get sponge iron power to be filtered and matched with raw material, dried to get sponge iron balls.
Time: 8
