Process of treating aluminum-containing fused slag |
March 22, 1988 |
| A method of recovering a metallic aluminum from an aluminum-containing slag of an aluminum smelting process. In this method, the slag is crushed a number of times with each crushing product being separated by a screening off removing the metallic aluminum before the next crushing stage. |
