| Abstract: | One kind of new production craft was proposed,namely got jointly with the sodium hydroxide and the hydrofluoric acid in the normal temperature to process,the iron the silicon,the titanium oxide compound from alumia.The results showed that the content of bauxite in the product was up to 94 %,which can be used as the fire-proof raw material.Therefore,this kind of new production craft could have the latent use prospect. |
| Keywords: | alumia hydrofluoricacid sodiumthydroxide bauxite removing impurity |
