| Abstract: | The valuable metals： iron, aluminum, calcium, sodium and silicon, were separated from Bayer red mud by roasting with ammonium salt, water soaking, acid leaching etc. Their compounds such as ferric oxide, aluminum sulfate, gypsum and sodium silicate were obtained. Influences of the roasting, water soaking and acid leaching processes on composition of Bayer red mud were investigated. The technique and technological conditions of separating the iron, aluminum, calcium, sodium and silicon from Bayer red mud were explored. Compositions and the phases of the prepared samples were analyzed. |
