| Abstract: | The captioned red mud is a byproduct during the production of alumina. The content of iron in the mud is 30 percent. It is found that through baking and reduction, it is possible to recover the iron. The optimal conditions are given as follows： ratios between red mud, calcium carbonate and charcoal being 5 ： 5 ： 1 ; reduction temperature being 1000 centigrade Celsius; baking time being 60 minutes. |
