In our country, the ash discharge of large aluminum each year, take the land and large accumulation harm. On the other hand, aluminum ash contains a large metal aluminium and alumina, but as the renewable resources. Our country at present the aluminum ash low recovery processing, energy consumption is big, should vigorously develop new technology and use of foreign advanced technology, equipment to change the backward state. Research and development from industrial aluminum slag, aluminum ashes recycling aluminum technology, not only protect the environment, and for recycling of aluminum, fully realize the concept of circular economy.
