SLUDGE-FREE PRODUCTION OF PURE ALUMINA FROM ROCKS CONTAINING IRON OXIDES AND SILICA
نویسندگان
چکیده
It has been established that the extraction of aluminum from rocks containing large amounts alkali-soluble silicates and iron oxides can be processed by acid-alkali method, except for formation wasted sludge. The carried out thermodynamic analysis showed possibility carrying process reduction a mixture sulphate salts with hydrogen. optimal conditions sulphates hydrogen have found production S2 SO2 stub in gas phase. Pure is obtained stubby Bayer method

Preparation of Alumina Nanorods from Chromium-Containing Alumina Sludge
Alumina nanorods were prepared from chromium-containing alumina sludge, and the effects of doping elements, such as Cr, Fe, and Mg, were researched. The results show that the crystal transformation of alumina is restricted by the doped Cr and facilitated by the doped Fe and Mg, which is transformed from θ-Al2O3 to α-Al2O3 in the calcination process. Meanwhile, the crystal transformation of alum...

متن کاملAlumina and silica oxides as catalysts for the oxidation of benzoins to benzils under solvent-free conditions.
Alumina or silica gel are used as catalysts for a solvent-free oxidation of benzoins to the corresponding benzils. These catalysts are easily recovered after completion of the reactions, which are carried out either by heating in a sand bath or using microwave irradiation. Comparison of the results obtained with both catalysts indicates that all the reactants examined were oxidized faster on al...
